SubprocessUIFactory & QUIFactory lack several important methods

[Alexander Belchenko]

SubprocessUIFactory has only get_password methods, but there is many other user-interaction methods which we should support otherwise some commands seems to hang. E.g. see https://bugs.launchpad.net/bugs/418252, new qrun command hang on interactive commands like break-lock which are used get_boolean IMO.

So, looking at bzr.dev/bzrlib/ui/text.py I see there is following methods we are lacking:

get_boolean(self, prompt)
get_non_echoed_password(self) ???
get_username

non_echoed password used by get_password which we re-implement. But it's possible some code uses it directly (bzr-svn?).

I don't think we have to implement get_non_echoed_password.
