chore: Add all newer configuration items to Environment Variable mapping.

[ata-nas]

Description

What happened

Currently, there is some missing support for some configurable values via environment variables.

What should to happen

In order to support environment variables for configuration classes, we need to map the conventional screaming snake case for environment variables (since still by default we are not able to get another case at runtime) to a convention the config api understands(e.g. MEDIATOR_RING_BUFFER_SIZE to mediator.ringBufferSize). This is done by updating the com.hedera.block.server.config.ServerMappedConfigSourceInitializer#MAPPINGS and we also need to update the respective awareness test com.hedera.block.server.config.ServerMappedConfigSourceInitializerTest#SUPPORTED_MAPPINGS. Also, alongside that, we should update the README.md to let the users know what are the correct screaming snake case keys for the configs.

Tasklist

• Update all the other needed configurations that need to be supported to be set via environment variables in :server
• Update all the other needed configurations that need to be supported to be set via environment variables in :simulator

Missing configuration that should be added:

• From server:
  • producer.type → PRODUCER_TYPE (default: "PRODUCTION")
  • mediator.type → MEDIATOR_TYPE (default: "PRODUCTION")
• From simulator:
  • From GrpcConfig.java:
    • grpc.serverAddress (default: "localhost")
    • grpc.port (default: 8080)
  • From BlockStreamConfig.java:
    • blockStream.simulatorMode (default: "PUBLISHER")
    • blockStream.delayBetweenBlockItems (default: 1_500_000)
    • blockStream.maxBlockItemsToStream (default: 100_000)
    • blockStream.streamingMode (default: "MILLIS_PER_BLOCK")
    • blockStream.millisecondsPerBlock (default: 1000)
    • blockStream.blockItemsBatchSize (default: 1000)
  • From BlockGeneratorConfig.java:
    • generator.generationMode (default: "DIR")
    • generator.folderRootPath (default: "")
    • generator.managerImplementation (default: "BlockAsFileBlockStreamManager")
    • generator.paddedLength (default: 36)
    • generator.fileExtension (default: ".blk.gz")
    • generator.startBlockNumber (default: 1)
    • generator.endBlockNumber (default: -1)

This is already merged, closing it.

This is already merged, closing it.

@AlfredoG87 no, this should not be closed as it is not implemented/merged anywhere.

In the above description, it is given example of an already existing config in order to showcase what must be done to all the others that need to be supported via environment variables. This issue IS NOT about the example above, but for all the rest.

I am reopening this. I also add a couple of checkboxes to make it more clear.
