Tags filter on masson commands

[Pierrotws]

propose the option -t to filter using tag in addition to module and host

Ex:

bin/masson install -t role=master -t environment=dev

[wdavidw]

I know, I had the same idea, but first, we need to re-write constrains

[Pierrotws]

Also, constraints are not constraints (since the operator used for multiple tags is an OR, not an AND).
Must be renammed.

[wdavidw]

No, must be re-implemented with AND. Not a priority before masson 2
