Publish oper_status time to STATE_DB (#3756)

Why I did it
Mentioned in sonic-net/sonic-utilities#3956 oper error status last timestamp always shows 'Never' because we never publish the time it last changed.

Port Errors                     Count  Last timestamp(UTC)
----------------------------  -------  ---------------------
code group error                    0  Never

oper error status                   3  Never

How I did it
Published the time to STATE_DB under oper_error_status_time
