Closes #52614

Use Gitaly 0.125.1

See merge request gitlab-org/gitlab-ce!22364

The check was if the job `has_environment` which results into showing
the environment information when the job stops the environment. This
result into having a blank `deployment_status`.

Use `starts_environment?` to be the same as the haml we have in 11.3

Remove the inheritance from ::BaseService which is causing us to inherit
the initializer that has project as the first arg, as we will not have
access to project with forthcoming group clusters.

Also call install service from create service - 1 less thing to re-use

Extract TestRequest code into a spec helper. Given that we need
different behaviour for Rails 5.0 (and again in Rails 5.1!), it's handy
to have that branching behaviour in one place

This should help with code re-use when we create applications for group
level cluster next.

Change `find_or_initialize_by` to explicitly find or build the right
association based on the application name. The benefit here is that we
use the associations on @cluster rather than querying from the other
side of the association.
