CLI for Configuring PFC Historical Statistics

[peterbailey-arista]

What I did

Added support for the followingcommands:

• config pfc-stat-history status <enable|disable>
• config pfc-stat-history start <ports|all>
• config pfc-stat-history stop <ports|all>
• config pfc-stat-history interval <milliseconds>
• show pfc-stat-history config

These changes were made for the PFC Historical Statistics feature: sonic-net/SONiC#1904

How I did it

• Added a pfc-stat-history group to config cli
• Added a pfc-stat-history group to show cli

How to verify it

• Run the sonic-utilities unit tests
• Run config pfc-stat-history <command> on a switch, verify the configurations with show pfc-stat-history config

New command output (if the output of a command-line utility has changed)

Example output of show pfc-stat-history config:

Namespace: asic0

-------------------  -------
POLL_INTERVAL        1000
FLEX_COUNTER_STATUS  disable
