High: DRBD: remove deprecated drbd agent.

Linbit packages their own drbd ocf agent outside of the
resource-agents upstream repo.  The drbd agent in the heartbeat
provider is deprecated in favor of the Linbit provider one.
Low: LVM: Fixes formatting mixture of tabs and spaces
Medium: LVM: Verify setup on start plus verify exclusive activation is possible.
Low: LVM: Refactor logic that builds activation options into separate function
Fix: LVM: Retry deactivating vg allowing udev to settle
High: LVM: Retry exclusive activation after deactivating vg cluster-wide
Low: named: Properly detect rndc stop failure

Launching rndc into the background meant we can't
access the return code easily without doing a wait
on the rndc pid.
Medium: named: Attempt to autogen /etc/rndc.key using rndc-confgen tool

This allows rndc to be used to stop and reload named without additional
configuration.
Low: apache: Fixes inconsistent formatting
Low: apache: Refactor apache_stop code to reduce complexity and indentation
High: LVM: Exclusive activation without clvmd using filtering with tags.
Medium: LVM: Warn user if initrd is older than lvm.conf when using exclusive activation with tags
High: apache: Attempt graceful stop before -TERM signal

Attempt graceful stop first with WINCH signal.

Low: fix VirtualDomain syntax error for very picky shells

The $(( was interpreted as arithmetic expression,
but it is meant to be a $( command substitution with a (subshell).
Medium: iSCSILogicalUnit: add tgt specific parameters bstype, bsoflags, device_type

This allows pacemaker to tell tgt to use aio, or O_DIRECT, or
scsi-generic or whatnot. See tgtadm(8) for possibilities.
