In the list of involved nodes, drop "no secondary"

When grouping moves into jobs, a new job set is started, if the new
move involves a node also touched by a previous move. When computing
the list of involved nodes, the new primary and secondary nodes of the...

Move saving of a command list to CLI

Move the function that saves a list of a command in a file

hsqueeze: support planing for onlining nodes

If the amount of free resources falls below a given threshold,
hsqueeze will suggest putting standby nodes back online until
the minimum of free resources is reached, or all standby nodes
are online.

Add an --minimal-resources option

Add a new option, to be used by hsqueeze, to specify
the amount of free resources that has to be on each
node, in order not to start onlining standby nodes.
It is given as a multiple of the standard allocation,
as specified by the instance policy....

Text Backend: correctly read data for offline nodes

With standby nodes, simply ignoring the specification of
an offline node is not sufficient any more.

Change default for target resource to 2.0

The target resources, as used by hsqueeze, are supposed to
be strictly higher than the minimal resources. However,
keeping minimal resources of less than a single instance
is not a useful reserve.

Add hsqueeze planning for compression

Add a new htool, hsqueeze, for dynamic power management. This
commit only implements the first useful part: plan (but not
executing) taking nodes offline nodes still keeping within the
resource limit.

Provide --target-resources option

Add a new option, to be used by hsqueeze, to specify the
target free resources on each node. It is given as a multiple

Merge 'EvacNode' and 'NodeEvacMode'

Merge 'EvacMode' and 'NodeEvacMode' which are associated with the
duplicated constants 'IALLOCATOR_NEVAC_*' and 'NODE_EVAC_*'. This
merge moves the type 'EvacMode' to 'Ganeti.Types' in order to avoid a
circular dependency between 'Ganeti.HsConstants' and...
