go routines removed but writing to kafka is still done via go routines


<Please press edit button to view in proper formatting>
The go routines related to port , device , transition state and kafka writing was removed from the voltha core and the PONC scale test performance was compared with the voltha core keeping the go routines intact.
The tests were carried out for an average of 5 runs with :
NUM_OLTS=6
NUM_ONUS_PER_PON=32
STACK_COUNT=1
NUM_PON_PORTS=16
The table below shows the performance in different cases:


| Test suite                            | with go routine                                          | without go routine(only port and device op goroutine removed) | without go routine(port and device op go routine removed,tansition state processing,kafka writing is in go routine) | without go routine(port and device operation ,transition state processing and kafka writing go routine removed) | without go routine(port and device op and tansition state processing go routine removed ,only kafka writing is in go routine) |
