Created by: stavamichal
Some changes about using /opt/perun/bin/ for pre/mid/post scripts
- use scripts from both paths /opt/perun/bin/{service}.d/ and
/etc/perun/{service}.d/
- if two scripts has the same name, higher priority has new path script
- change path to lib to /opt/perun/lib/{service}/ from
'process-{service}'
- Fix Makefile and generator of RPM to use right path (wrong path is
/opt/perun/bin/process-{service}.d/ and
/opt/perun/lib/process-{service}/
- add info to all affected changelogs
- fix ldap and ldap-svb-vi scripts to work with new correct paths
