Pass netinfo in rpcs
If a nic has a network field then encapsulate a network object innetinfo slot for every rpc. This is needed to pass network info toscripts managing nics (kvm-vif-bridge).
Introduce _BuildNetworkEnv().

Update blockdev's "info" at instance rename
Currently, we set "info" metadata on block devices at device creationtime, but we never update it, leading to stale data in case ofinstance renames. This would not be a big problem in case of regularrenames (assuming this is a rare operation), but importing instances...

Annotate disk params on instance_start
We call _GatherAndLinkBlockDevs during the process, which in turncalls _RecursiveFindBD. This needs disk parameters to work.
See also commit b8291e0.
This was reported by Ansgar and Damien.

Move necessary constants from rpc & rpc_defs to constants
As timeout constants will now be used also on Haskell side, they havebeen moved from rpc_defs and rpc to constants. The same is true forconnection timeout for connecting to nodes.

Bump pep8 version to 1.2
Debian Wheezy will ship with this version, and it has many improved checks compared to 0.6, so let's:
- bump version in the docs- silence some new checks that are wrong due to our indent=2 instead of 4- fix lots of errors in the code where the indentation was wrong by 1...

Fix DRBD resize code
There are two bugs in the current resize code, affecting mostly DRBD.
First, due to bugs in old DRBD versions (pre 8.0.14), the code currentlycalls `drbdsetup resize' on both the primary or secondary. However,this is actually wrong per current DRBD (from drbdsetup(8)):...
Annotate disk params on instance_os_add
We call _OpenRealBD during the process and this needs disk parameters towork. This was reported by Constantinos.
The fix is very ugly though.

Not annotating them works for DRBD but not for RBD as reported byConstantinos.
