Description of problem:
JBoss CLI process creates aesh log files under the tmp directory when it runs. However, JBoss CLI's logging flag for the aesh log is false. It means that JBoss CLI does not output any log for these files and these files remain even if the JBoss CLI process shuts down.

Version-Release number of selected component (if applicable):
EAP 6.4.1

Steps to Reproduce:
1.Run JBoss CLI
2.Stop JBoss CLI
3.You can confirm aesh logs in the tmp directory like below.
~~~
/tmp $ls 
-rw-rw-r-- 1 xxxx xxxxx     0 Jun 30 16:55 aesh.log.1
-rw-rw-r-- 1 xxxx xxxxx     0 Jun 30 16:55 aesh.log.1.lck
-rw-rw-r-- 1 xxxx xxxxx     0 Jun 30 16:55 aesh.log
-rw-rw-r-- 1 xxxx xxxxx     0 Jun 30 16:55 aesh.log.lck
~~~

Additional info:
aesh log files increase with the number of running JBoss CLI process. If this logs are not necessary for JBoss CLI, the customer wants not to create it on JBoss CLI process.
