The current open file limit of 1024 is not enough when executing
operations that involve a large amount of subclouds in parallel
(e.g. patching orchestration). dcmanager-audit already has its limit
increased through the existing global option 'worker_rlimit_nofile',
but the other services are not using this option.
This commit moves the function that sets the limit to the utils.py
module and makes the other dcmanager services use the defined limit.
Test Plan:
1. PASS - Verify that the open file limit gets updated to the defined
value by checking the service log file and by verifying the
/proc/<pid>/limits file;
2. PASS - Verify that the new limit it enough to support DC patch
orchestration with MAX_SUBCLOUD_GROUP_MAX_PARALLEL_SUBCLOUDS
subclouds;
3. PASS - Verify that the limit can be changed by modifying the
/etc/dcmanager/dcmanager.conf file with worker_rlimit_nofile
option;
4. PASS - Verify that it's not possible to increase the soft limit past
the hard limit.
