Add a build info metric file
Summary
In order to expose the installed omnibus version to Prometheus, we should include a version file that can be exposed by the node_exporter's textfile collector0.
Proposal
Include a Prometheus formatted info metric to allow monitoring of which version of omnibus is installed on each node.
# HELP omnibus_build_info The build version information
# TYPE omnibus_build_info gauge
omnibus_build_info{branch="master",revision="53279f21",version="10.6.xxxx"} 1
