chore: bump version to 0.17.0 and add upgrade guide

[roderickvd]

This PR is to launch the v0.17 release train.

If possible I'd like to slip in the following PRs:

• #1058

[roderickvd]

I tested all bevy examples while patching this branch and rodio's too and everything seems to be working as expected.

Thanks for the feedback. Shall we slip in #1070 too, have you tested with Bevy even if you could not reproduce the original issue?

I tested both the snippet example provided in that issue and bevy examples but could not reproduce it for versions 0.15 and 0.16. I'm not sure if it's an OS version thing, if it's device related or maybe a patched 0.15 version of cpal fixed it, which the poster of the issue was not using. They were using bevy 0.13.2 which in turn used cpal 0.15 and rodio 0.17 as far as I could see.

I haven't tested your fix though, I can do so later.

Last call for testing: aiming for asio-sys 0.2.4 and cpal 0.17 release tomorrow.
