[autotest] Add POE support to RPM server
Add POE support to RPM server. This allows us to hard reset
beaglebones utilizing the RPM server.
The core implementation resides in POEController in rpm_controller.py
To find out to which switch a servo is connected to,
we store the mapping information(servo->switch) in a csv-formatted file.
The file name is specified in rpm_config.ini.
rpm_dispatcher is modified to route poe requests to POEController instances.
Once rpm_dispatcher is initialized, it loads the mapping file to a dictionary
and uses it to determine the switch hostname and interface for a servo.
Simple integration tests are added in rpm_controller.py
Unit tests are added in rpm_controller_unittest.py
utils_unittest.py is added to test util functions in utils.py
servo-interface-mapping.csv should be updated if configuration
in switches changes.
BUG=chromium:232614
TEST=ran rpm_controller_unittest.py, rpm_dispacher_unittest.py,
frontend_server_unittest.py, utils_unittest.py, integration tests
in rpm_controller.py, test_client.py, and ran frontend_server.py,
rpm_dispatcher, rpm_client locally.
