ceph-disk: set the default systemd unit timeout to 3h

Browse Source 
There needs to be a timeout to prevent ceph-disk from hanging
forever. But there is no good reason to set it to a value that is less
than a few hours.

Each OSD activation needs to happen in sequence and not in parallel,
reason why there is a global activation lock.

It would be possible, when an OSD is using a device that is not
otherwise used by another OSD (i.e. they do not share an SSD journal
device etc.), to run all activations in parallel. It would however
require a more extensive modification of ceph-disk to avoid any chances
of races.
