* Improve Azure startup time and fix command palette
- Improvement (but not full fix) for #4732 where Azure startup is very slow.
This speeds the startup by up to 5 seconds by
- Changing from fixed 5 second initial wait time to a promise to check for accounts
- Using the accounts changed notification to send a message when accounts are ready. This is usually what will "win out" since Azure seems to load before the Account Providers are set up.
- Remove right-click actions from the command palette.
- Rename Azure actions so it's clear what they are in the command palette.
* Remove coveralls task while investigating how to make optional task
* Add void return type
VSCode serialization changed rejection handling to only serialize errors, which caused things to break
- Changed to return either account info or a cancel message in the resolve
- Rewrote to use promises. Tracking how to return canceled through 4+ thenables was way trickier than just using a promise
- Updated unit tests to handle new scenario
- Tested integration tests, realized they a) didn't run and b) didn't passed.
- Added vscode dev dependency to fix run issue
- Fixed tests to account for behavior changes in tree state.
