/**
 * Logs details like full exception stack trace for failed Hystrix commands.
 * A command might not have been executed (say threadpool/semaphore rejected,
 * short circuited). Command might have been executed but failed (say timed out,
 * command execution failed).
 *
 * This is required as Phantom's RequestLogger logs failures of sync command
 * executions alone (and not async command executions) and doesn't provide request
 * level view of all commands.
 *
 * We log global headers here as it typically contains request id
