Installation push tracking

[alexblack]

Records push status per Installation, in a new class Push with fields:

• installation
• pushStatus
• result
• deviceToken

Logic:

1. A new Push object is created for each (Installation, PushStatusId) when sending pushes to the push adapter
2. After the push adapter returns, each of those objects is updated with a result

Result scenarios for each push:

1. No deviceToken found on installation
2. No result from adapter for installation
3. Result from adapter

npm run test passed locally, but looks like there is an issue causing a test to fail. I'll look at fixing that up.

Seems that your feature break compatibly with the postgres adapter...

[alexblack]

Yes :( Is there a way for me to test that out locally? It seems that npm run test didn't catch the problem for me.

We're undergoing a major refactor of the push architecture with #3080.

Closing for now, as the refactor will completely break with that PR.
