> When the server mentioned in bootstrap.servers property in kafka appender are not available.
> For e.g. Unable to resolve DNS etc.
> The application isn't starting and the java process terminates after trying to connect to the server.
> Failure to initialize the appender should not block the application process and other appenders, just like file appender, for e.g. when file path is not resolvable, it moves forward.
> Attached log4j2.xml. 
> Tried wrapping it in async appender as well, does not provide expected result as the issue is with initialization of appender.
