Merge ppa-dev-tools:set-command-private-ppa into ppa-dev-tools:main

[Bryce Harrington]

Implements support for creating private PPAs and toggling PPAs public vs. private.

Creating private PPAs requires special authorization that I don't seem to have, with the result that I've not been able to verify that this actually works correctly "live". However, I've included checks for some of the authorization errors I've hit, and implemented a slew of unit tests. I'll try to find someone with access to do the live verification, but apart from that I think this code is ready for review and landing.

As usual, to run the testsuite, do:

    $ make check

or

    $ pytest-3

And the smoketest has been updated to include toggling --private:

    $ ./tests/smoketest_ppa_set

However as mentioned, unless you have authorization to modify privacy on PPAs that will merely generate errors.

LGTM! just one note for one of the help strings

review: Approve

Thanks Lena, I've squashed that change in, updated this branch, and landed to main.
