Initial version of CMIP7 submission code

[Matthew Mizielinski (matthew-mizielinski)]

Closes #751

Added:

• CMIP7 configuration file with list of facet maps [1].
• CMIP7 queues
• logging information when constructing message content in dds.py (_prepare_message)
• alternative variable filtering in drs.py (filter_filesets)
• changes to ensure that moose client understands commands clearly
• allowed reading of approved variables files for CMIP7

Removed:

• CMIP6 queues (defunct)
• old archiving code (send_to_mass, rerun_send_to_mass) and associated tests
• use of both body and content in messages throughout the code now just have content.

Note: rabbitMQ tests can only be run from systems with access to rabbitMQ servers.
