Patch 0001 (master and sssd-1-8):
Allow increasing the file-descriptor limit
This patch will increase the file descriptor limit to 8k or the
limits.conf maximum, whichever is lesser.
Patch 0002 (master only):
Make the file descriptor limit configurable.
This code will now attempt first to see if it has privilege to set
the value as specified, and if not it will fall back to the
previous behavior. So on systems with the CAP_SYS_RESOURCE
capability granted to SSSD, it will be able to ignore the
limits.conf hard limit.
