repo/ubuntu: allow to change uca repo name

UCA proposes two kinds of repositories:
'proposed': not stable release but enough to be tested
'updates': considered as stable release (default)

'updates' is default to keep backward compatibility.
Using 'proposed' would be useful to test the current trunk release of
OpenStack if UCA is providing packages for it.
