VOL-2191: Implement the right interpretation of instance-control attribute
from tech-profile
- When using "single-instance" type TP, make sure no other gem-port on any
other UNI port is referncing the same alloc-id before releasing the alloc-id.
- When deleting tech-profile instances for the ONU, log any errors with deleting
any TP instance, but do not break the loop (so that other TP instances can be
freed up).
- Use 2.2.17 version of voltha-lib-go
