Install Promtool

[lswith]

We should install the promtool so that configuration can be checked before reloading the service.

./promtool -help
usage: promtool <command> [<args>]

Available commands:
  check-config    validate configuration files for correctness
  check-rules     validate rule files for correctness
  help            prints this help text
  version         print the version of this binary

Only a link should be sufficient since the promtool is already in the prometheus binary distribution. On my systems I found it on /opt/staging/prometheus-${version}.linux-amd64/

[lswith]

that is correct. I was thinking more if we should run it before we restart the service?

[brutus333]

I believe we can run it before reloading or restarting the service. It may be a good idea. However, it will complicate a bit the startup scripts.
