- 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
