Add Abode entity available property

[shred86]

Proposed change

Adds the available property to Abode entities. This PR goes with some changes required to Abodepy which I have a pull request open for. The available property is updated based on the status of the web socket connection to Abode's servers.

Also adds the PlatformNotReady exception if the integration setup fails due to a connection issue. I can move this to a separate PR if desired but it's a one line change.

This should not be merged until my Abodepy pull request is merged and I bump the Abodepy version.
The reason I'm making this PR now is to get feedback since the two PRs work together.

CI Failure is unrelated

homeassistant/components/zone/__init__.py:240: error: unused 'type: ignore' comment

[bdraco]

Approved, subject to upstream change being merged and a re-run of the CI

[bdraco]

@shred86 mentioned more changes are coming. I'll come back for another review pass later.

[shred86]

Finally figured out a fix to a small issue I was having. Just waiting for my PR in abodepy to be merged then I'll make a commit to this PR to bump the abodepy version and it should be good to go.

[bdraco]

@shred86 Is this still waiting for upstream?

I'm assuming its this one MisterWil/abodepy#67

[shred86]

I am. I sent @MisterWil a message on Discord but haven't heard from him yet. Once that upstream PR is merged, this should be good to go.

[shred86]

PR was merged on abodepy. Just made a commit to bump the abodepy version.

hass.async_add_job is legacy for general use. Either use hass.async_create_task to schedule coroutines or hass.async_add_executor_job to schedule functions that need to run in the executor thread pool.

I'll fix this in a new PR, thanks!
