Also remove repository_replication_spec.rb as it's more accurately covered by http_push_spec.rb

- Project#lfs_http_url_to_repo() returns #http_url_to_repo()
- EE::Project#lfs_http_url_to_repo() returns #http_url_to_repo() if isn't a Geo secondary with a primary, otherwise, returns Geo primary project HTTP URL
- Use Project#lfs_http_url_to_repo() in API /internal/lfs_authenticate

Added specs for #deploy_key_pushable?() and #type()

LfsToken::HMACToken#token_valid?() will be examined and if false, look
in redis via LfsToken::LegacyRedisDeviseToken#token_valid?().

Closes gitlab-ce#51676

See merge request gitlab-org/gitlab-ee!8612

Currently, if a job does not have only/except policies, the policy is considered as an unspecified state, and therefore the job is executed regardless of how it's executed and which branch/tags are targetted.
Ideally, this should be specified as only: ['branches', 'tags'], as it indicates that unspecified policy jobs are meant to run on any git references.

It appears that for some jobs
(https://gitlab.com/gitlab-org/gitlab-ce/-/jobs/129705025 for example)
we process a range of commits far greater than necessary, which can lead
to commits getting reverted that were merged a long time ago.
