Adding Cassandra client proto version as config option

[iamrodrigo]

What changed?
ProtoVersion can now be defined in development.yaml. If not present, the default value will be 4.

Why?
Labeled as Up for grabs as good first issue in #3536

How did you test it?
Playing with some values in the development.yaml file. Happy to add some unit test if you indicate me where

Potential risks
There was a default value set in newCassandraCluster, however the value is sent by value and not by reference so it won't be set somewhere else. Potentially the right place would be tools/cassandra/handler.go but please let me know where you think I should set this value in case this is not the right place

Release notes
Maybe? Let me know if you want me to do that

Documentation Changes
Likely to be the case. Let me know if I need to do this.

Hi @vytautas-karpavicius, friendly ping to review this :)

[vytautas-karpavicius]

Looks good.

@yycptt I've addressed your comments and also modified other files where Protoversion might be needed.

Two things to add:

1. I don't know if this is related to my change but I'm getting an error when I run make bins. This is not allowing me to run the test in local

common/types/mapper/thrift/shared.go:3415:3: unknown field 'NextEventId' in struct literal of type shared.PollForDecisionTaskResponse
common/types/mapper/thrift/shared.go:3439:31: t.GetNextEventId undefined (type *shared.PollForDecisionTaskResponse has no field or method GetNextEventId)

2. The change is quite big already (not only to review but to merge). I'm happy to split this in smaller changes if you want me to (i.e add compatibility first and then modified config files)

I think make bins failed because the IDL submodule is changed to an old version so the generated thrift files are also changed. The build and test should pass once you updated the IDL to the latest commit 68a720ef059629a0cba5db58f71053100acb7f19 by using git submodule update --remote
