Provide configuration to override Geo sync URL
Description
By default the GitLab Geo secondary node uses the external_url from the primary node for cloning repositories (see ssh_url_to_repo)
This can cause issues if the user wishes to use a different URL to clone (sync) from, for example a hostname instead of the FQDN (external_url).
Proposal
Provide an additional advanced configuration option to override the Geo SSH or HTTP clone URL.
UI Example
gitlab.rb example
geo_secondary['primary_clone_url'] = 'hostname'Use cases
This use case applies to instances behind a proxy that blocks port 22. Cloning is only available via HTTPS
Example 1: Non-working example
Example 2: Working example
Currently as only the external_url can be used the Geo secondary node cannot connect directly via gitlab-primary.local and must connect via gitlab-public.example.com
