GEODE-10231 : Add configuration for suppressing FunctionException logging

[zsitole]

Jira: https://issues.apache.org/jira/browse/GEODE-10231
Problem:
The function executed on a server can throw FunctionException by the contract. Geode servers are logging all exceptions with stack trace to warn/error log level and respond error back to the client. But huge number of FunctionException thrown from user functions logged in geode server can affect performance, use disc space for the logs storage, and can complicate the analysis of log files.

Solution 1:
The improvement for server side logging is adding system property configuration for surprising FunctionException logging. With enabled property, all FunctionException caused by user functions will be logged to debug log level.

System property for suppressing FunctionException logging:
gemfire.logging.suppressFunctionExceptionLogging=true

Solution 2:
Add Log4j markers for all FunctionException logs to be able to handle them by Log4j filter configuration, eg. disable all function exception logs:
<MarkerFilter marker="FUNCTION_EXCEPTION_MARKER" onMatch="DENY" onMismatch="NEUTRAL"/>

• Has your PR been rebased against the latest commit within the target branch (typically develop)?

• Is your initial contribution a single, squashed commit?

• Does gradlew build run cleanly?

• Have you written or updated unit tests to verify your changes?

• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?

If the exception is thrown back to the caller, we do not need to log it in info/warning level (because down the calling stack, someone else should log it), but if we are turning it into some other form (only sending down the message to the caller), then we should log it in its entirety. I hate to have support turn on "debug" logging in order to see what's going on.

We need documentation for this feature in page: https://geode.apache.org/docs/guide/113/managing/logging/configuring_log4j2.html and https://geode.apache.org/docs/guide/114/developing/function_exec/function_execution.html
