[Starlingx-discuss] Upcoming removal of pip's legacy resolver

[Scott Little]

Thanks for the heads up Jeremy

I've scanned the current master branch code base an fount the following 
hits.
All are found in 'tox.ini' files.  We can expect...
- Build failures due to failed unit tests
- Zuul to vote -q on code reviews in some repos

Most commit messages acknowledge that the use of '--use-deprecated 
legacy-resolver'
is a quick fix, and that followup will be required to deal with 
dependency conflicts.
