Description of problem:
request ID is a 5 chars long (or rather short) hex string. This can be too small for more busier Satellites, where the same request ID can be repeated soon. Like I see in a customer's logfile:

2018-12-12T03:48:27 [I|app|e02d7] Processing by Katello::Api::V2::RootController#rhsm_resource_list as JSON

The extra Processing/Completed belong to a different request, coincidentally with the request ID of same value.

Those "duplicates" confuse investigation and makes troubles to bulk searching / processing the logs (i.e. here I wanted to find out the longest response time of "GET /rhsm/" requests, but some other "Completed" loglines apparently appear..).


Please make the request ID longer, such that probability of hitting such duplicate request ID in one file is significantly smaller.


Version-Release number of selected component (if applicable):
Sat 6.4


How reproducible:
???


Steps to Reproduce:
1. Generate many requests against Satellite, the smaller the better

2. Check for uniques of the requests, e.g.:
grep Completed /var/log/foreman/production.log | awk '{ print $2 }' | sort | uniq -c | sort -n | tail


Actual results:
2. shows duplicate request IDs, like:
      4 [I|app|fcff4]
      5 [I|app|30d04]
      5 [I|app|56d3e]
      5 [I|app|57028]
      5 [I|app|c622e]
      5 [I|app|c6a30]
      5 [I|app|c8391]
      5 [I|app|eabcb]
      5 [I|app|f23ba]
      5 [I|app|f2e65]

Expected results:
2. to show just unique requests IDs, like:
      1 [I|app|00008]
      1 [I|app|00014]
      1 [I|app|00017]
      1 [I|app|00022]
..
