- Closes#60024
- Change PrometheusClient.new to accept a base url instead of an
already created RestClient
- Use Gitlab::HTTP in PrometheusClient instead of creating RestClient
in PrometheusService
- Move http_options from PrometheusService to
PrometheusClient (follow_redirects: false)
- ensure that base urls don't have the trailing slash
- Created a `PrometheusClient#url` method that might not be strictly
required
- Change rescued exceptions from RestClient::* to
HTTParty::ResponseError where possible and StandardError for the
rest
- Also refactor the get and json_api_get methods so that the get method
can be reused by the new proxy method.
- The new proxy method makes no changes to the request to the prometheus
server and response from the prometheus server. This allows it to be
used as a proxy to the Prometheus server, hence the name.
