Permit config shadowing

To support the idea that diverse zuul installations can share common
job definitions in a 'standard library' project, but still be able to
override some job definitions with their own local versions if needed,
add a tenant config option to permit a repo to shadow another one.

Place the local project first in configuration, then on the remote project,
indicate that it shadows the local one.  Then, any definitions in the
remote repository which conflict with the local will be ignored.
