Fix remove_source_branch merge request API handling

Closes #60530

See merge request gitlab-org/gitlab-ce!27392

- Externalize strings for desc and explanation
- Update PO file

Users attempting to set merge requests to `remove_source_branch` to
`false` would encounter an Error 500 because the UpdateService and API
checked `present?`, which would always return `false`. We now just
use `has_key?` to decide whether the parameter is present.

Add variable substitution in prometheus proxy API

See merge request gitlab-org/gitlab-ce!27226

- In prometheus proxy api, allow variables to be replaced. For example,
if 'up{env="%{ci_environment_slug}"}' is passed to the endpoint, it
becomes 'up{env="production"}' before being sent to prometheus.

When deleting a pipeline, only some of the cache structures were being
expired, but not the full pipeline list. We have to synchronously
schedule a pipeline cache expiration because the pipeline will be
deleted if the Sidekiq expiration job picks it up. To do this, properly
extract all the logic buried in the Sidekiq worker into a service, and
then call the service.
