Move the `objects` method to `LfsHelper` so that it is also available to `LfsStorageController`

Move the `objects` method to `LfsHelper` so that it is also available to `LfsStorageController`

It is needed for the `lfs_check_access!` callback when the repository size limit is enabled (EE only).

Omniauth auto link LDAP user falls back to find by DN when user cannot be found by uid

Unfortunately, SAML IDs can be an LDAP UID, DN, or something else entirely. UID and DN are most common, though. This adds a fallback scenario so we first try to find a matching LDAP user by UID, then by DN. This will fix a problem for the customer in https://gitlab.zendesk.com/agent/tickets/43298

Resolve "Introduce round-robin project creation to spread load over multiple shards"

Allow multiple shards to be enabled in the admin settings page, balancing project creation across all enabled shards.

* `f.select ..., multiple: true` isn't the most beautiful UI in the world, but switching to `collection_check_boxes` (or a facsimile thereof) isn't trivial
* Should `pick_repository_storage` be a method of `ApplicationSetting`, or `Project`? It's going to accrete logic over time so perhaps it should be its own class already?
* This is written to avoid the need for a database migration, so it is`serialize :repository_storage` without `, Array`. This is tested, but alternatives include:
  * Add a database migration
  * Write a custom Coder that will accept a String or Array in `load` and always `dump an Array.

disable markdown in comments when referencing disabled features

This MR prevents the following references when tool is disabled:

- issues
- snippets
- commits - when repo is disabled
- commit range - when repo is disabled
- milestones

This MR does not prevent references to repository files, since they are just markdown links and don't leak
information.
