Move duplicated Cargo dependencies to the root workspace manifest, switch member crates to workspace dependencies, and align non-conflicting shared feature sets at the workspace level.
Upgrade a number of shared dependencies while consolidating versions across the workspace. This also consolidates the ldap3 dependency in response to GHSA-qcxq-75wr-5cm8: https://github.com/kanidm/ldap3/security/advisories/GHSA-qcxq-75wr-5cm8
Update frontend and migration code for dependency upgrades and clean up manifest structure.
Add a subschema entry to the rootDSE, which shows all attributes and
objectclasses present on the LLDAP server, which is needed for some
applications that need to index the LDAP server. The current
implementation's goal is to have a bare minimum working subschema which
follows the LDAP RFC. It also updates the GraphQL interface to follow
the changes that have been made in actually separating out
objectclasses, instead of having them as an attribute.
