Python2 removed during install

[Bryan Quigley]

Python2 is removed during the install (but some things that seem to still depend on it our still installed).

ibus-sunpinyin seems to be the package holding it in the livecd itself - but that's removed if you don't pick a language it is related to (didn't confirm that it stays if you pick language X).

I expect if python2 is available on the liveCD it to the be available in the installed environment too.

Ideally, we could just drop python2 from the livecd though.

Note: libpython2.7 remains on the installed environment due to something here- gnome-control-center* gvfs-backends* libsmbclient* python-talloc* samba-libs* ubuntu-desktop*.

As discussed in #ubuntu-desktop, this is intentional. We have been trying to get python2 out of the default install for years.

Besides ibus-sunpinyin, cifs-utils also ends up pulling python-samba (and python2). None of those packages are needed for most people after install and so are removed at the end of the install process. But we do want them in the live environment for now.

If you find a package that doesn't work without python2 installed and doesn't depend on python2, please file a bug against that package. LP: #1721394 is an example of a bug like that.
