Removed call to setup, which can cause problems

Added script to allow importing large TSV files into FireCloud

This script was calling setup(), which all other scripts do - but since it's a script to register and only uses the svc account credentials, it doesn't make sense to print who you are authed is.  Someone was running this with an account that wasn't registered with FC and got an error, but it would have run if setup was not called.

otherwise fail to upload.  This does imports in chunks of smaller files.

Added auth script to help switch app default credentials ...

service accounts with these scripts.

Added in a script to rebind output values from a given submission
in case that failed to work properly.

Ab methods repo groups and tsv for large entities

from the data tab and a script to use a file with a list of emails to
synchronize permissions on a method/config in the repo

Added script for registering a service account and a script to show

the estimated storage costs for workspaces in a project.

Modified the big query billing report to handle larger submissions
and deal with some token expiration issues.
