The *victoria-metrics* role deploys a single-server instance of the
Victoria Metrics time series database server. It installs the selected
version by downloading the binary release from Github and copying it to
`/usr/local/sbin` on the managed node. Scrape configuration is optional
and can be specified with the `scrape_configs` variable.
Encrypting the vault password with GPG protects the key when stored on
disk and allows it to be accessed non-interactively, as long as the
GnuPG agent is set up correctly.
