[Chore] Make activation wait timeout configurable

Problem: Currently profile activation waiting timeout is hardcoded to
240 seconds, see #48.
In some cases, this timeout can be exceeded (e.g.
activation performs a heavy DB migration and waits for it to finish
before considering the profile activation succesful).

Solution: Make this timeout configurable via 'activationTimeout' deploy
attribute or corresponding '--activation-timeout' CLI option. For the
sake of backward compatibility, the new 'wait' subcommand
'--activation-timeout' option is made optional and defaults to 240
seconds if it wasn't provided.
