Kendall Nelson c5e3d8affb Splitting Out Connectors from connector.py
This is a larger refactor of the connector.py file. The goal is to
simplfy the file by moving the vendor connector classes to their own
files, and keep only the InitiatorConnector in the connector.py file.
The vendor specific connector tests are also split out into their own
files.

Change-Id: I020e75ca8cd8bec2ad1b38f3ade5cc1f63a4fee5
Implements: bp connector-refactor
