Add classes to check excess storage size

See merge request gitlab-org/gitlab!45155

Add classes to calculate and check the excess storage size of a
namespace/group.

We want to start importing Group and Project data directly from
another GitLab instance, via the API. To do this, we need somewhere
to store a mapping between the source entity and the destination
entity.

Create the Entity model which is associated with a BulkImport,
and used to store the data required to link the entity (project or
group) on the source instance and the destination instance.

This model introduces:

1. `bulk_import_id` -> the bulk import that this data belongs to.
2. `parent_id` -> the parent ImportEntity that this one should be
   imported into
3. `source_type` -> what kind of entity this is (group or project)
4. `source_full_path` -> path to access the entity on the source
5. `destination_name` -> what to call the entity on the when it's
   created
6. `destination_namespace` -> where to store the entity on the
   destination.
7. `status` -> for use with the state machine to determine the import
   status of this entity
8. `jid` -> the job ID of the sidekiq job that will/has processed this
   import.

Issue: https://gitlab.com/gitlab-org/gitlab/-/issues/250280

We want to start importing Group and Project data directly from
another GitLab instance, via the API. To do this, we need somewhere
to store authentication data so that we can execute the import in
background jobs.

Create the BulkImport::Configuration model which is associated with
a BulkImport, and used to store the authentication data for the
source GitLab instance. This will be followed up by the
introduction of the other models the store the import data.

This model introduces:

1. `bulk_import_id` -> the bulk import that this configuration
   applies to.
2. `api_url` -> the domain for the source instance.
3. `access_token` -> the personal access token of the user on the
   source instance for authentication.

Issue: https://gitlab.com/gitlab-org/gitlab/-/issues/250280

We want to start importing Group and Project data directly from
another GitLab instance, via the API. To do this, we need somewhere
to store authentication data, entity mapping data and other metadata
so that we can perform the import in background jobs.

Create the BulkImport model which is associated with a user, and used to
group together all the data relating to the one bulk import request from
the user. This will be followed up by the introduction of the other
models the store the import data.

This model introduces:

1. `source_type` -> where the data for this import is being sourced
   from. For now this will just be GitLab imports, but in the future we
   could expand this structure to other services like GitHub and
   Bitbucket.
2. `user_id` -> the user that initiated the import.
3. `status` -> to be used by the state machine for recording the status
   of the overall import.
