Migrations and server bootstrap are very interconnected processes
and in this we'll be addressing and improving both.
Server bootstrap was performed by creating base entries in phases,
eventually bringing up enough of the *oldest* supported server
minimum remigration level, to then allow triggering of migrations.
Migrations then applied "patches" effectively ontop of this minimum
level to update entries to what they should be in newer versions of
the server.
This scheme has it's pros and cons, but the major con was that to
remove a migration meant squashing it's content back into the
minimum remigration level, and this was a human process that was
quite error prone and difficult to automate. As well, this scheme
also led to cases where the patch migrations would sometimes *not*
reflect all the needed changes or content, or in one case was actually
undone by a patchlevel fix up that was required to address a bug.
Invariably this led to issues, and cases where a new server may have
different content to a migrated one - not exactly what we want!
This is a new migration scheme that addresses this fragility. However
what it trades is verbosity of the content.
Rather than having a base set of entries and patching/updating small
sections ontop, we have migration data folders that contain the full
set of entries as they should appear at that migration level. This
makes the bootstrap process easier as we can just apply the migration
level as a whole, and targetted to what precise version we want.
This also makes migrations more durable as the content is explicitly
copied and all entries fully applied, so there is no risk that a
migration or data change can be forgotten or applied incorrectly. We
are expressing the full state of what our builtin and provided entries
should be.
Finally this rips out a number of places where migration data was being
used as test case data. Not all of these have been replaced (notably
in authsession with Account), but the majority have and have been replaced
with clearer use of constants rather than building whole entries just to
access the name and throw them away for example.

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.

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.
Fixes#2601Fixes#393 - gid numbers can be part of the systemd nspawn range.
Previously we allocated gid numbers based on the fact that uid_t is a u32, so we allowed 65536 through u32::max. However, there are two major issues with this that I didn't realise. The first is that anything greater than i32::max (2147483648) can confuse the linux kernel.
The second is that systemd allocates 524288 through 1879048191 to itself for nspawn.
This leaves with with only a few usable ranges.
1000 through 60000
60578 through 61183
65520 through 65533
65536 through 524287
1879048192 through 2147483647
The last range being the largest is the natural and obvious area we should allocate from. This happens to nicely fall in the pattern of 0x7000_0000 through 0x7fff_ffff which allows us to take the last 24 bits of the uuid then applying a bit mask we can ensure that we end up in this range.
There are now two major issues.
We have now changed our validation code to enforce a tighter range, but we may have already allocated users into these ranges.
External systems like FreeIPA allocated uid/gid numbers with reckless abandon directly into these ranges.
As a result we need to make two concessions.
We *secretly* still allow manual allocation of id's from 65536 through to 1879048191 which is the nspawn container range. This happens to be the range that freeipa allocates into. We will never generate an ID in this range, but we will allow it to ease imports since the users of these ranges already have shown they 'don't care' about that range. This also affects SCIM imports for longer term migrations.
Second is id's that fall outside the valid ranges. In the extremely unlikely event this has occurred, a startup migration has been added to regenerate these id values for affected entries to prevent upgrade issues.
An accidental effect of this is freeing up the range 524288 to 1879048191 for other subuid uses.

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
