snapcraft 2.17 has been released

[Sergio Schvezov]

Hello snapcrafters!

We are pleased to announce the release of version `2.17` of snapcraft:
https://launchpad.net/snapcraft/+milestone/2.17

The highlights in this release are:

- A `python` plugin rewrite, combining the `python2` and `python3` 
plugins into one.  This new plugin creates
   leaner snaps, works better with regards to build environments, 
separates `stage-packages` from package brought
   in with `pip` and solves many latent bugs from the previous 
incantation of the python plugins.
- More assertion related goodies, `snapcraft-register-key` and 
`snapcraft list-keys` are new commands added
   to this release.
- The `organize` keyword for parts now supports globbing.

As usual there is a regular set of bugfixes in this release too. Those 
can be seen in the milestone referred to.

This release has seen many contributions from outside of the snapcraft
core team, so we want to give a shout out to these folks, here's a team
thank you for:

- Alexandre Abreu
- Colin Watson
- Sam Yaple

To consume the latest snapcraft release on Xenial Xerus (16.04), we
