Release 2.0

[Temikus]

Ok, let's do this. @erjohnso PTAL

Tested #180 - looking good 👍

Since we're entering 2.0, will implement 2 additional breaking changes:

• image parameter will no longer default to an arbitrary one. Not setting it will throw a user-friendly error. Since the image/image_family logic is dealt with in zone-specific config, this will greatly simplify things. Provider-level configuration shouldn't have contained that information in the first place as it's executed multiple times and will cause collisions if the zone parameter is set at runtime (like image family). Fixes #144

• Upgrading to new standard SyncedFolders action and removing old rsync code. This time it should be ok as I finally found a proper workaround - all test pass ^___^ Fixes #158, #152, #137, #109, #94, #87

Made some drive-by fixes as well:

• Fix disk cleanup issue causing the disk to be marked as created before insertion. Fixes #148
• Test environment fixups to avoid 'Encoded files can't be
• read outside of the Vagrant installer.'
• Fixes to ssh control flow. Fixes #104

Was testing this release locally and found a small issue: for some reason I can't specify the location of the GCE key using ~/... anymore. I have to specify the full, absolute path to my home directory now.

@zackangelo Thanks for catching this! Should be fixed now.
