Have a field in the variables for autocomplete

[zbal]

Some of the fields in the services need to be marked as eligible to autocomplete. Need to define which one, and make it usable by the frontend.

Applies to:

• services' variables
• packages' tasks' options

ex.

• backend listening port of haproxy = nginx listening port (and vice versa) -- need autocomplete ability
• openvpn protocol (udp/tcp) has no point in being autocompleted.

Note: the ex. above are example are WRONG - but give an example of what may be autocompleted and what may not

[zbal]

I believe anything is autocompletable and instead of adding an extra param in the definition we should simply let the user add anything; the frontend autocomplete logic should catch a regex and suggest variables among its pool of available variable instead.
