remove ADR-038 plugin system due to AppHash error

[egaxhaj]

Description

The current implementation of ADR-038 - State Listening plugin system results in an AppHash mismatch error when implemented in the Provenance blockchain. This PR removes the implementation from the forked release branch as it is not usable. In addition, the plugin system uses Kafka as one of its services which currently does not have support for Apple M1 chips and requires some manual installation processes that make it difficult for Provenance clients to build and run the binary even when they're not using the plugin system. The ADR-038 implementation will eventually come from upstream so removing it will also keep the release-pio/v0.45.x branch clean.

NOTE: There is a PR in place to implement a lighter version directly into the Provenance API that borrows from ADR-038.

Closes: #XXXX
