Use 389-ds provided method for file limits tuning
Previously IPA would set the LimitNOFILE value to 8192 to increase
the number of concurrent clients. 389-ds-base does this by default
as of 188.8.131.52.
Remove the IPA-specific tuning and rely on the out-of-the-box
Bump the required version of 389-ds-base to 184.108.40.206.
Any other tuning added by 389-ds-base will result in a
dirsrv.systemd.rpmsave file which admins will need to merge
in manually, like typical .rpmsave config changes.
