Closes #800

What this PR does / why we need it:
Part3 for task#800, to remove Logger from eventHub under resource manager.

Special notes for your reviewer:
Before the change, the files under eventhugs with 'Logger' parameters.

grep -r "logr.Logger" ./pkg/resourcemanager/eventhubs/ -l
./pkg/resourcemanager/eventhubs//consumergroup.go
./pkg/resourcemanager/eventhubs//namespace.go

After the change,

grep -r "logr.Logger" ./pkg/resourcemanager/eventhubs/ -l

It is not feasible to test the modified code though, tested the create/delete eventhub namespace, eventhub and consumergroup.
