log: fix timeout when deleting configuration stream [#2903]
During closing stream, log sevice does try again in 8s when renaming file.
the log server is hung in that time and cannot poll and process any
requests.
If the completed_callback come from imm in that time, the callback cannot be
processed in time (in 6s) and cause timeout issue happen.
The try again in 8s should be remove to avoid hanging any requests. And
specialy
here is to avoid timeout of callback requests from imm

** [tickets:#2903] log: timeout when deleting configuration stream by immcfg
-d**
**Status:** fixed
**Milestone:** 5.18.09
**Created:** Mon Jul 30, 2018 07:36 AM UTC by Canh Truong
**Last Updated:** Thu Aug 30, 2018 12:45 PM UTC

Steps:
1/ create cfg stream 1
- immcfg -c SaLogStreamConfig safLgStrCfg=Test1 -a saLogStreamPathName=. -a
saLogStreamFileName=Test1
2/ create cfg stream 2
- immcfg -c SaLogStreamConfig safLgStrCfg=Test2 -a saLogStreamPathName=. -a
saLogStreamFileName=Test2
3/ Delete stream 1
- immcfg -d safLgStrCfg=Test1
4/ Delete stream 2
- immcfg -d safLgStrCfg=Test2
- In step 3 , ccb_apply_callback_delete is called (from log service)when
deleting stream 1. The callback take 8 second to do try again renaming file.
imm return command "immcfg -d" before the callback has done.
- In step 4, ccb_comleted_callback is call (from log service) when deleting
stream 2. the request to call the completed callback is sent to log mbx. But
now log service is processing the renaming (in step3). Imm just wait 6seconds
for the repons of completed_callback. So the completed callback has not been
processed in 6s, and imm has not got the response of this callback. ==> Timeout
issue happen
