Removing SVN download of LIT due to MonoRepo

[drew_maxwell]

Summary

Removing need to acquire LIT via SVN copy, as LIT is now provided in the MonoRepo.

[cmatthews]

How is the lit requirement no longer needed? This URL does not work, but the we still require lit to be installed for the system to work. I think this needed to be updated to fetch the latest lit from the GitHub repo.

Where does this file come from?

lit is packaged on pypi, would it work to get it from there?

[cmatthews]

In the past there has been rev lock between LNT and LIT, so we try to fetch the most up to date lit we can. The pypi version can be quite out of date.

[drew_maxwell]

Replaced SVN checkout with installation via current updated Monorepo

[cmatthews]

Can you remove the commented out old line. Otherwise, LGTM.

[drew_maxwell]

Removed previously commented-out line.

[drew_maxwell]

Removed the errant mypatch.patch file from the previous commit.

[drew_maxwell]

Confirmed removal of SVN line from requirements.client.txt. Removed reference from comment as well.

Just to confirm, you are using git+git not git+https?

Both were tested successfully. Either one could be used; is there a preference?

[drew_maxwell]

Changed protocol used from Git to HTTPS.

[cmatthews]

LGTM
