Configured prometheus client to reuse TCP connections to the pushgateway (#21695) 
ref
https://linear.app/ghost/issue/ENG-1796/reuse-tcp-connections-when-sending-metrics-to-the-pushgateway

- When we rolled out the prometheus metrics collection, it overwhelmed
the pushgateway. Our hypothesis is that Ghost was creating too many new
TCP connections to the pushgateway.
- The prometheus client was creating a new connection with the
pushgateway each time it pushed metrics every 15 seconds.
- This commit changes the prometheus client to keep the connection
alive, and re-use it instead of creating a new one.
- It also limits the number of retries if pushing the metrics fails —
after 3 consecutive failures, Ghost will stop retrying and log an error.
