[0.6.0] Support for EVMConnect and FireFly v1.1.x

[onelapahead]

Includes a new firefly-evmconnect chart so that multiple installations of EVMConnect can be made for different Ethereum-based chains (public or private).

The core firefly chart is then updated to include creating a single installation of evmconnect, and migrate the presumably existing default multi-party namespace to the new v1.1.x namespace config format (see the relevant FIR and migration guide) while allowing for new, additional namespaces to be defined with however many additional plugins may be needed (via config.extraDatabases, config.extraBlockchains, etc.). Similarly, if users created other multi-party namespaces in their v1.0.x installations of FireFly, they will be able to define and migrate them using config.extraNamespaces.

ethconnect support within the chart is then deprecated in favor of evmconnect. And lastly, the ability to connect to both evmconnect and a remote Fabconnect is supported with the choice of which to use for the default namespace. This allows users to create a multi-party namespace based on Fabric, but then have a gateway or additional multi-party namespace pointed to an Ethereum chain for example.

TODOs

• ci/ files for EVMConnect
• Further test
• Finish docs

[onelapahead]

Determined that fixing the E2E test and docs might have to be saved for separate PRs so that this can be merged to create a release candidate once Fabric testing is complete.

Commenting to indicate my review/approval.

Using a local-values.yaml like the one below (secrets redacted) and remote Kaleido blockchain environments I confirmed I could run Fabric and Ethereum multi-party namespaces in tandem with a local EVMConnect and have the node register itself within both:
