(triggering pthread_create failures) on a ~2000 OSD cluster.
Increasing this resolves it!

The libexec path is different for different distributions.
systemd. This path is defined by a new variable on the
configure path.
This variable can be set with enviroment SYSTEMD_LIBEXEC_DIR.
The parameter --with-systemd-libexec-dir overrides the enviroment
variable.
Appropriate conditionals are set for SUSE and RHEL derivatives.
This is then used to template out systemd/ceph-osd@.service

This patch adds systemd service files. It is possible to start and
enable multiple instances (per monid, osdid, mds name), e.g.
# systemctl start ceph-mon@node01
# systemctl enable ceph-mon@node01
# systemctl start ceph-osd@0
# systemctl enable ceph-osd@0
The ceph cluster can be set in the system config file:
/etc/sysconfig/ceph
adding or editing the CLUSTER environment variable.
