Special var CLI_SILENT / CLI_VERBOSE

[hans-d]

Like CLI_FORCE, would be great to have a CLI_SILENT and CLI_VERBOSE. This allows to play with the command verbosity.

cmds:
- do-x {{- if .CLI_VERBOSE }} -v {{ end -}}
- do-y | tee out.log {{- if .CLI_SILENT }} | head -n 3 {{ end -}}

Hi @hans-d,

Agreed. This should be simple to implement, so I added the good first issue label in case anyone wants to contribute.
