Update the dev_path on LVs on rename

When renaming a logical volume, we should change the dev_path (and other
internal variables) in order to be consistent.

Allow drbd8 devices to work without local storage

This patch adds functionality to drbd8 for:
- removing local storage
- initializing without local storage
- adding local storage

This is needed for the being able to replace disks for drbd8.

Implement block device renaming

This patch add code for renaming a device; more precisely, for changing
the unique_id of the device. This means:
- logical volumes, rename the volume
- drbd8, change the remote peer

This is needed for the being able to replace disks for drbd8....

Modify two mirror-device related rpc calls

The two calls mirror_addchild and mirror_removechild take only one child

disk replacement in drbd8, we need to be able to specify both the data...

Initial implementation of drbd8 template type

This is a partially working drbd8 template type. It does:
- add/remove
- startup/failover/shutdown

Not working is replace disks, which needs custom code for this template.

Allow DRBD8 to sync after sb1-pri with no changes

Currently the way we shutdown or startup disks seems to make DRBD8
unhappy. Until we rewrite the sequence of (de)activation, allow DRBD to
connect after a sb1-pri condition with no changes to the data.

Add DRBD8 class for handling drbd version 8.x

This duplicates some code from the DRBDev class, but not very much, and
it will be expanded with the new functionality available for the 8.x
version. Currently the code is not accessible outside the module.

This patch introduces a dependency on the pyparsing module....

Move/rename _IsValidMeta to base drbd class

The DRBDev._IsValidMeta only checks for the metadata device size. Since
this is a useful check (but not complete) for DRBD8, move it to the base
class and name it _CheckMetaSize.

Improve out-of-minors handling

Currently, the out-of-minors handling is not very good: though both MD

DRBD code checks for this case.

Move some methods from DRBDev to BaseDRBD

Since some of the methods and constants are valid for both 0.7 and 8.x

Split some DRBD functionality based on versions

This is a small split of some functionality from the DRBDev class into a
base drbd class that holds just a few things, in order to make migration

Abstract more strings values into constants

Currently, the disk types are defined using constants in the code.
Convert those into constants so that we can easily find them and check

Remove the shebang from modules

Since modules are not directly executables, remove the shebang from
them. This helps with lintian warnings.

Also make the autogenerated _autoconf.py contain two comment lines at
the beginning, like the other modules.
