To support Redfish interface for hardware control.

Add new mgt type ‘redfish’. Definition: mgt=redfish

Use the same table with openbmc, “#node,bmc,consport,taggedvlan,username,password,comments,disable".

/opt/xcat/lib/perl/xCAT_plugin/redfish.pm

/opt/xcat/lib/perl/xCAT/AGENT.pm (move agent related part from /opt/xcat/lib/perl/xCAT/OPENBMC.pm here)

/opt/xcat/lib/python/agent/xcatagent/redfish.py

/opt/xcat/lib/python/agent/hwctl/executor/redfish_power.py

/opt/xcat/lib/python/agent/hwctl/redfish_client.py

The main code logic:

1. redfish.pm

• Handle xcat command. (rpower on)
• Check command and node definition error.
• Collect all nodes’ bmc, bmcip, bmcusername, bmcpassword
• Call AGENT.pm to call python agent

2. AGENT.pm

• Collect xcat attributes xcatdebugmode, verbose,cwd, envs
• Start agent.py and build socket with python part
• Send all information (nodes and xcat attributes) to python part
• Receive socket message from python part and print out

3. redfish.py

• Receive all info from perl part
• Parse and check args
• Deal with command, call corresponding task RedfishPowerTask and method to deal with subcommand

4. redfish_power.py

• Send request and receive response data by calling redfish_client.py
• Deal with response data to send message back to perl

5. redfish_client.py

• Do real work of send request and receive response by requests method
• Deal with response, check error and raise error

RedfishPowerTask is sub class of ParallelNodesCommand, call gevent to deal with command for each node at the same time.
