Pull v1.0.2 of syslog-ng configuration submodule.
Allow multiple UCARP options to be set.

To support a "preferred" UCARP master (or master switch-back) the
UCARP configuration on the preferred master requires (apart from a lower
advertisement interval, base and skew) the --preempt option to be set.
This leads to different UCARP configurations on the primary master and
secondary master nodes. Thus, we switch to a more general replacement
pattern which allows the node-configuration script to set as many
options as it needs to.
Set nice (=-5) and ionice (=real-time) priorities to avoid failover on busy systems

* move FOSS-Cloud_CA to openssl subfolder since this repo is still an
  overlay
* Remove manual keep files since we will 'keepdir' the directories in
  the ebuild
Rename again: /etc/ssl instead of /etc/openssl
