[Metrics] Triton server should expose software version / build number as a prometheus metric

[Kellel]

Is your feature request related to a problem? Please describe.
Being able to check the current deployed versions of software ensures that updates are completed correctly

Describe the solution you'd like
version number baked into the binary on build
build_info metric exposed via prometheus that includes version/build_time/etc

Describe alternatives you've considered
It's possible to scrape the docker versions, but tags can be somewhat unreliable and can be changed

Hi @Kellel , thanks for suggestion! I'll file a feature request for our team.

Taking a look at this.

I don't currently know how to get or expose build time so if someone can point me in the right direction I'd appreciate it.

Hi @Kellel,

If you're just looking for the version of Triton that is currently running, is the server metadata endpoint sufficient?

$ curl -s localhost:8000/v2 | jq
{
  "name": "triton",
  "version": "2.42.0",
...
}
