David Teigland 7f29afdb06 lvmlockd: configurable sanlock lease sizes on 4K disks
New config setting sanlock_align_size can be used to configure
the sanlock lease size that lvmlockd will use on 4K disks.

By default, lvmlockd and sanlock use 8MiB align_size (lease size)
on 4K disks, which supports up to 2000 hosts (and max host_id.)

This can be reduced to 1, 2 or 4 (in MiB), to reduce lease i/o.
The reduced sizes correspond to smaller max hosts/host_id:

1 MiB = 250 hosts
2 MiB = 500 hosts
4 MiB = 1000 hosts
8 MiB = 2000 hosts (default)

(Disks with 512 byte sectors always use 1MiB leases and support
2000 hosts/host_id, and are not affected by this.)
