Move misc packages into pkg package

This is one of the main bits of feedback from @stefanprodan
that was still remaining after consolidating the two
controllers.

This patch also removes the service namespace field from
the scale type. The value can and is read from the query
string, meaning that this field was redundant and non-standard
compared with the types in faas-provider.

Tested with go test ./... and with make using the Dockerfile.

Tune the verbosity as per pre 0.12.0

This retains the verbose print of configuration at start-up, but
puts it behind a flag.

Switch from OF client to OF lister interface

**What**
- Use the informer/lister to get Profiles instead of the REST client,
  this should be more efficient and low impact on the k8s API because it
  maintains an internal cache of the profiles

Update apply REST handler

The HTTP handler appeared to generate errors with the latest
versions of Kubernetes (1.17.5 and 1.18). A function created
via REST and then updated via a CRD or visa-versa caused an
error about the RevisionVersion being required.

By getting the function object before updating it, this
appears to resolve the issue.
