Hi @anxumalo, @mbujak-hyland,

In case you wonder what this PR is about, this is a set of URL rewrites to have links now pointing to the new Nexus3 URl pattern after we migrated from NXRM2 to NXRM3 a few weeks backs.
Old URL still work due to redirections we've setup but as we plan to further change the archiecture and would like to avoid carrying over legacy stuff we'd like to have these links changed.

@alxgomz Thanks for the heads-up and extra info. @pmacius had already contacted me about it, so we'll include it on our next release.
