Code Issues Proposed changes

Enable git protocol v2 in container images 

Git versions between 2.18 and 2.26 have version 2 protocol support
but it's not enabled by default. Starting in 2.26, it is the
default.  V2 is more efficient at negotiating refs and can reduce
the time spent updating a repo by 50% on large repos.

This adds a setting to the container images to specify that v2
should be used.  The images are currently built with git 2.20, which
is in the range where this is needed.
