Advanced Service Discovery in Prometheus 0.14.0

Prometheus v0.14.0 introduces enhanced service discovery capabilities, adding native support for Consul and a file-based interface for custom discovery mechanisms alongside existing DNS-SRV support. This allows Prometheus to dynamically locate and monitor targets based on various service registries. The release also features improved label manipulation through relabeling, offering greater flexibility in configuring how targets are identified and grouped for monitoring, and allows for runtime configuration reloads with a SIGHUP signal.
