[receiver/solacereceiver] Added configurable flow control interval, baggage unmarshalling

[mcardy]

Description:

1. Updated payload unmarshalling to include baggage supporting Solace PubSub+ Event Broker version 10.2.1
2. Added configuration knob for flow control retry interval and stats to help tune interval

Link to tracking Issue: N/A

Testing: Updated tests accordingly to add tests for new unmarshalling behaviour, new configuration options and new stats.

Documentation: Added new section for flow control configuration in README, bumped status to beta since configuration should now be stable.

@djaglowski seems both test runs failed with

make[1]: Leaving directory '/home/runner/work/opentelemetry-collector-contrib/opentelemetry-collector-contrib/receiver/riakreceiver'
make[1]: *** [../../Makefile.Common:77: do-integration-tests-with-cover] Error 1
make: *** [Makefile:169: receiver/riakreceiver] Error 2
Error: Process completed with exit code 2.

I don't know how my changes would have affected this. My tests pass locally. I'm going to try and pull in the latest changes from main and see if that helps.

[TylerHelmuth]

Is updating the payload unmarshalling and the new flow control config related? Could they be broken into separate PRs?

[mcardy]

@TylerHelmuth we wanted to deliver both changes at the same time to align with the next release of our event broker and having a single artifact to validate is more straight forward for us. It would be somewhat of a pain to separate these out into two PRs at this point, but going forward we can strive to have work items in separate PRs if that is better for the review process.
