This patch changes the name of directory from mech_arista to arista

This name change of directroy is needed so that additional drivers
can be moved into this directory and share the code among drivers.

In order to accomodate this name change, setup.cfg is modified to
point to the Arista ML2 driver at the new location. Additionally,
a similar new directroy is created for test files as well.
