Add VALUE_AUTO and VALUE_GENERATE constants
'auto' is used in multiple place in the code with a meaning similar to'default', 'generate' will be used to force generation of mac addresseswhen the default would be to reuse an old one.

Some fixes related to auto_balance
Change the constant name to match the value (autobalance ->auto_balance).
Also add the auto_balance header so that gnt-instance can list it.

Memory is renamed for easier use.
Change gnt-instance list to the hvparams model
This is just a change of the various hvm_ and pvm parameters to the hvmodel. Parameters are queried via hv/$name or via the whole dict asreturned by hvparams.

Sanitize the hypervisor names
Since in 2.0 the user will possibly have more interaction with thehypervisor names, we sanitize them by removing the version numbers(the version can be a prerequisite for the ganeti installation, weshouldn't document it in variable names)....
Implement job 'waiting' status
Background: when we have multiple jobs in the queue (more than just afew), many of the jobs (up to the number of threads) will be in state'running', although many of them could be actually blocked, waiting forsome locks. This is not good, as one cannot easily see what is...

Enable the use of shared secrets
This patch enables the use of the shared secrets for DRBD8 disks, using(hardcoded in constants.py) the md5 digest algorithm.
