Add an API entry-point to the deployWorkspaceProject command

Closes #571

Will be leveraged by the Azure Functions extension.

Hey all, this should be ready for review again!

@nturinski Thanks for all the great feedback, I was able to take a step back and change up the implementation quite a bit in the spirit of your review.

I took your recommendation to decouple invokedFromApi from the old deployWorkspaceProject and went a step further. I actually ended up just completely removing that boolean and logic coupling altogether. Now instead of the api calling directly into deployWorkspaceProject... deployWorkspaceProjectApi calls directly into deployWorkspaceProjectInternal. This way deployWorkspaceProject and deployWorkspaceProjectInternal now have no concept of the API, and now you only need to look at the api function to completely understand how its parameters influence the overall behavior of the internal implementation.

For removing api references from the internal implementation - I exposed any related surfaces via toggle-able internal UI options. I was even able to consolidate the default context gathering logic into the internal implementation which I think really cleaned everything up quite a bit by allowing the API function to not have to call into deployWorkspaceProject as an outer command.

I also consolidated all output logs into the internal implementation to ensure uniform behavior regardless of entry-point. I took your recommendation and removed the references to API as well.

PR Breakdown

Added precursor PR covering the decoupling for the new internal implementation to reduce the amount of code to review in one sitting:
#585

I also have these two open PRs which will reduce the length of this PR by a few lines once merged:
#584
#583

Here's the setup PR in Functions to consume this API:
microsoft/vscode-azurefunctions#3934

Let me know if you think it would be a good idea to default some of these values

[nturinski]

Does this comment still make sense? A lot of this seems defaulted already.

nit: I prefer that we keep the apiProvider looking clean like so:

deployWorkspaceProject: deployWorkspaceProjectApi

And then in deployWorkspaceProjectApi, wrap that whole command with callWithTelemetryAndErrorHandling
