These are two very relevant tests for roaming / enterprise networks
that relied on custom attenuator setups. They rely on site_attenuator.py which was killed/moved in the below commit.
Check if these tests can be rewritten to use the new attenuator instead.

    autotest: Rewrite attenuator control logic
    
    Now all control logic runs on the remote server rather than being split
    between the server and beaglebone.  This makes the code generally more
    readable since concerns are not split across files.
    
    Updated the attenuator verification test and the RvR tests to reflect
    a slightly changed interface.
    
    TEST=RvR and verification tests work as expected.
