a3635abf1d Parse action profile max group size from P4Info annotations
This is a temporary workaround to the inability of p4c to
correctly interpret P4Runtime-defined @max_group_size annotations.

4c289b731d New P4RuntimeClient implementation that supports batching and error reporting
The new client API supports batching and provides detailed response for
write requests (e.g. if entity already exists when inserting), which was
not possible with the old one.

This patch includes:
- New more efficient implementation of P4RuntimeClient (no more locking,
use native gRPC executor, use stub deadlines)
- Ported all codecs to new AbstractCodec-based implementation (needed to
implement codec cache in the future)
- Uses batching in P4RuntimeFlowRuleProgrammable and
P4RuntimeGroupActionProgrammable
- Minor changes to PI framework runtime classes

99c59dbb03 ONOS-7898 Action profile group/member refactoring
Also includes:
- New abstract P4Runtime codec implementation. Currently used for action
profile members/groups encoding/deconding, the plan is to handle all
other codecs via this.
- Improved read requests in P4RuntimeClientImpl
- Removed handling of max group size in P4Runtime driver. Instead, added
modified group translator to specify a max group size by using
information from the pipeline model.

50d195ffb3 Do not insert or delete default action entries in P4Runtime
Spec says:
the default entry for a table is always set. It can be set at
compile-time by the P4 programmer - or defaults to NoAction (which is a
no-op) otherwise - and assuming it is not declared as const, can be
modified by the P4Runtime client. Because the default entry is always
set, we do not allow INSERT and DELETE updates on the default entry and
the P4Runtime server must return an INVALID_ARGUMENT error code if the
client attempts one.

With this patch we convert insert or delete operations into modify ones
(unless specified by a driver property, to support non-compliant devices).
For delete, we use the interpreter to suggest a default action that is
the same as the one when the pipeline was originally deployed.

Also, we introduce the capability of synchronizing the device mirror
with the device state.
