* Ignore tests that are no longer used.
Each time a library or binary is added, that requires compilation to create
the *empty* test harness, which then is executed and takes multiple seconds
to start up, do nothing, and return success.
This removes test's for libraries that aren't actually using or running
any tests.
Additionally, each time a new test binary is added, that adds a ton of
compilation time, but also test execution time as the binary for each
test runner must start up, execute, and shutdown. So this merges all
the testkit integration tests to a single running which significantly
speeds up test execution.
* Improve IDL exists behaviour, improve memberof verification
Again to improve test performance. This improves the validation of idx
existance to be a faster SQLite call, caches the results as needed.
Memberof was taking up a large amount of time in verify phases of test
finalisation, and so a better in memory version has been added.
* Disable TLS native roots when not needed
* Cleanup tests that are hitting native certs, or do nothing at all
Add the server side components for application passwords. This adds the needed datatypes and handling via the ldap components.
Admin tools will be in a follow up PR.

Thanks to @Seba-T's work with Orca, we were able to identify a number of performance issues in certain high load conditions.
This commit contains fixes for the following issues
* Unbounded Memory Growth - due to how ARCache works, to maintain temporal consistency it must retain copies of keys (not values) in a special data set for tracking. The Filter Resolve Cache was using unresolved filters as keys. This caused memory explosions when refint or memberof were updating a group with a large number of members because they would emit a query with hundreds of filter terms that would only be used once and never again, causing the ARCache haunted set to grow without bound. To limit this, we no longer cache large/complex queries for resolution, and in future we may implement some other methods to reduce this like sha256/hmac of the queries.
* When creating a new account, dyngroups would be engaged to add the account as a member due to the matching scope. However the change to the dyngroup was triggering an update of all the dyngroups *members* related memberof attributes. This would mean that adding an account would trigger every other account to be loaded an updated.
* When memberof would iterate over leaf entries and update them one at a time. This mean a large number of small fragmented queries in the case of a lot of leaf entries being updated. Now leaf entries are updated in a single stripe once groups are stabilised.
* Member of would always trigger it's members to always update. Instead, we should only update members where a difference is observed, or all members if the group's memberof itself has changed since this needs to propogate to all leaf entries. This significantly reduces the amount of writes and operations to examine the changed member of set.
* Referential integrity would examine all reference uuids on entries for validity rather than just the reference uuids that were altered within the transaction. This change means that only uuids that were *added* are validated during an operation.
* During async write backs (delayed actions) these were performed one at a time. Instead, when possible this should be done in a single transaction as the write transaction caches all writes in memory until the commit meaning that by batching we reduce overall latency.
* In the server there can only be one write transaction and many readers. These are guarded by tokio semaphores that act as fair queues - first in gets the lock next. Due to the design of the server readers would be blocked on the *database* semaphore, and writers would block on the write semaphore and THEN the database semaphore. This arrangement was creating a situation which unfairly advantaged readers over writers, as any write would first have to become the head of it's queue, and then compete with all readers to access a db transaction. Instead, we now have a reader semaphore with size threads minus 1, clamped at a minimum of 1. This means that provided there are two or more threads, then a writer will *always* have a database handle available, and readers will pre-queue with each other before queueing on the db ticket. If there is only one thread, then writes and reads will alternate between each other fairly.
While basking under the shade of the coolabah tree, I was overcome by an intense desire to improve the performance and memory usage of Kanidm.
This pr reduces a major source of repeated small clones, lowers default log level in testing, removes some trace fields that are both large and probably shouldn't be traced, and also changes some lto settings for release builds.

This completely reworks how we approach and handle cryptographic keys in Kanidm. This is needed as a foundation for replication coordination which will require handling and rotation of cryptographic keys in automated ways.
This change influences many other parts of the code base in it's implementation.
The primary influences are:
* Modification of how domain user signing keys are revoked or rotated.
* Merging of all existing service-account token keys are retired (retained) keys into the domain to simplify token signing and validation
* Allowing multiple configurations of local command line tools to swap between instances using disparate signing keys.
* Modification of key retrieval to be key id based (KID), removing the need to embed the JWK into tokens
A side effect of this change is that most user authentication sessions and oauth2 sessions will have to be re-established after upgrade. However we feel that session renewal after upgrade is an expected side effect of an upgrade.
In the future this lays the ground work to remove a large number of legacy key handling processes that have evolved, which will allow large parts of code to be removed.
This adds support for special-casing sessions in replication to allow them to internally trim and merge so that session revocations and creations are not lost between replicas.
Refers #1987
Notable changes:
- in server/lib/src/entry.rs - aiming to pass the enum instead of the strings
- changed signature of add_ava to take Attribute instead of &str (which is used in the entry_init macro... which was fun)
- set_ava<T> now takes Attribute
- added TryFrom<&AttrString> for Attribute
Himmelblau needs to maintain some data about the state of an authentication across the course of pam exchanges.
