Add `verbosity` level like [ v | vv | vvv ] ?

[gregberge]

Deployer - is for deploy in PHP like capistrano, like shipit(like capistrano). My proposal is:

-v|vv|vvv, --verbose Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

Other comands - https://deployer.org/docs/cli
