adding LACP attributes port priority and rate v1

[mkilar123]

Changes required to extend the interface configuration capabilities required by one of the Customers.
The change introduces the configuration options for two parameters related to LACP protocol:

• lacp_port_priority
• lacp_rate

Tested the parameters with a simple ansible task including following scenarios:
A: mode

• access port-channel
• trunk port-channel
• vpc access port-channel
• vpc trunk port-channel
  B:
• specifying non-default values
• specifying default values
• omitting the parameter in the task

Snippet of taks used for testing:
