Fixes #944 - Support wildcards on activationEvents.workspaceContains

[eamodio]

Here is a first pass at this -- I don't really like checking for wildcard/glob characters but it works as is and should be easy enough to change that part if the rest looks reasonable.

@eamodio, thanks for your PR! By analyzing the history of the files in this pull request, we identified @bpasero and @alexandrudima to be potential reviewers.

@alexandrudima I'm not sure why the builds are failing with these changes -- it builds locally. And looking at the travis one, I don't even see any failures. Any ideas?

[eamodio]

Apparently it just needed a kick

Any chance this could be looked at in the May iteration? I know the C# extension is really hoping to get this in.

[eamodio]

@alexandrudima sorry to bother you, but any feedback on this?

[alexdima]

@eamodio Thank you for your contribution! ❤️

@alexandrudima awesome! thank you!

Thanks, very cool!

Future improvement: This will run until the entire workspace has been searched, even if it finds a match immediately. You could use the progress callback on search to complete immediately once a match is found.

@roblourens doesn't this https://github.com/Microsoft/vscode/pull/24570/files#diff-7799696b0b4988cc737acff368fad1b1R140 make it return after the first match?

[roblourens]

Oh right, yes :)
