Add function to get the moves between two configurations

Add a function that, given two adjacent cluster configurations of
a balancing sequence, computes the moves that led from the first
to the second configuration.

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...

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...

Support big-step shrinking in tiered allocation

In tiered allocation, if by shrinking only a single resource a valid
allocation can be found, shrinking is bound to shrink on this resource.
Of course, after shrinking that resource a little bit without finding...

Index instances by their UUID

No longer index instances by their name but by their UUID in the cluster

adjustments were necessary: * Change the index key to UUID in the configuration and the...

In tiered allocation, cut non-promising shrinking tries

The heuristics for tiered allocation has been improved in that it
chooses to shrink such a resource next where by shrinking only this
resource a valid allocation can be made, if such a resource exists....

Improve hspace shrinking strategy

In tired allocation, hspace shrinks that resource of the instance
next, that causes failure on most nodes. While, this is not a bad
strategy in general, it can lead hspace into a dead end if for a large
number of nodes a particular resource blocks any further allocation of...

hspace prints info about spindles

Statistics about spindles are tracked. In human-readable output, spindles
are printed only when used (i.e., exclusive storage is enabled). For
machine-oriented output, they are always there.

Check real spindles in ipolicies

When exclusive storage is enabled, the spindles in instance disks are used
to check the instance policies (as outlined in design-partitioned.rst).

Add tests for network-aware allocation

hail-alloc-invalid-network defines a cluster with two nodegroups and an
allocation request which does not fit on any of the groups. Group 1 has
invalid disk-templates while Group 2 is not connected to the right

Honor network connections in hail

Before trying to allocate nodes in node groups, node groups are now

Remove use of 'head' and add hlint warning for it

Since 'head' is unsafe to use in most cases, this patch removes its
use from most of the code, adds a lint warning for it (and for tail as
well), and adds override annotations in the few cases where it's
actually OK to use it (mainly when using head over the result of...

Rename htools/ to src/

Per offline discussions, this is the first patch of the
renames. Tested with "make distcheck", seems to work fine.

The only change outside of the renaming is a bit of simplification in
the .gitignore rules; otherwise, simply s/htools/src/....
