cli: add option --same-sudo-password

[philippemilink]

To tell all hosts in the inventory uses the same password, which will be prompted only once.

In my setup, all SSH hosts of my inventory have the same sudo password. The problem is that when I run an operation which requires sudo on all my inventory, I am prompted to give the sudo password for each host, and all the prompts are somehow mixed on the same line:

I don't want to put the sudo password as a parameter of pyinfra command (to avoid leaking it in my shell history), but rather I want to be prompted, but only once.

So this PR adds the option --same-sudo-password to prompt for sudo password only once at the beginning of the execution.
