[enhancement]: Support Sparse Checkout

[bdovaz]

Describe your feature request here

For monorepo repositories this is a must to be able to speed up builds as much as possible.

I see that this very thing has been recently merged by @dscho into the GitHub checkout action: actions/checkout#1369

Would this same functionality be possible in azure pipelines?

Thanks!

Hi @bdovaz thanks for the reporting! We're currently working on higher priority issues, but we'll get back this this one soon.

Note that the actions/checkout PR relies on partial clones to be supported server-side, something that Azure Repos could only do via emulation using the GVFS protocol (which so far is only supported using Microsoft's Git fork, which is not installed on the build agents by default).

Note that partial clones are now supported by Azure Repos!

Although it is an improvement, it has nothing to do with the purpose of this issue.

The big improvement would be that at a high level through the checkout task we can make a sparse checkout indicating the directories to include as you can do in Github from your PR from half a year ago.

any way to bump priority on this one?

monorepos consume agent time uselessly doing full checkouts...
