image metadata files have been written to:
/Volumes/WorkHD/Users/jbeedy/juju/juju_meta/images/streams/v1.
For Juju to use this metadata, the files need to be put into the
image metadata search path. There are 2 options:

1. Use the --metadata-source parameter when bootstrapping:
   juju bootstrap --metadata-source /Volumes/WorkHD/Users/jbeedy/juju/juju_meta/

2. Use image-metadata-url in $JUJU_HOME/environments.yaml
Configure a http server to serve the contents of
/Volumes/WorkHD/Users/jbeedy/juju/juju_meta/
and set the value of image-metadata-url accordingly.
