### Description
### Troubleshooting
By executing an external script using exec_cmd function I'm getting the following
error:
``failed. exit_status=13, errno=11: Resource temporarily unavailable``
This is happening intermittently, sometimes it's working fine, but sometimes I see
this error in the log file. After looking in the debug log file I found that for some
reason the exit code for the executed command is not 0 (ki_exec_cmd(): execution return
code: 1), that's why this function is complaining (I guess).
What is weird that this is not happening permanently, it's about 2 cases from 5, and
by running the same command manually - every time I'm getting success, all the time
exit code is 0. (I'm running the same command with the same user like kamailio is
running)
Replacing exec_cmd with exec_avp - I didn't notice this issue.

Use exec_avp instead
