Add an --minimal-resources option
Add a new option, to be used by hsqueeze, to specifythe amount of free resources that has to be on eachnode, in order not to start onlining standby nodes.It is given as a multiple of the standard allocation,as specified by the instance policy....
Change default for target resource to 2.0
The target resources, as used by hsqueeze, are supposed tobe strictly higher than the minimal resources. However,keeping minimal resources of less than a single instanceis not a useful reserve.

Fetch data from MonD to HTools
Contact all MonDs from HTools to fetch data from its DataCollectors (only CPUload Data Collector is queried at themoment). This information is available to all HTools with the--mond option and can be ignored if the --ignore-dynu option is...
Define a new option --ignore-dynu
This option, if set, will tell htools to ignore any dynamicuse data.

hroller: option --full-evacuation
Add an option to hroller, to plan for full evacuation of thenodes to be rebooted, i.e., also plan for replacement secondarynodes for all instances on the node after migrating out instanceswith this node as primary.

add option --print-moves to hroller
If non-redundant instances are present in the cluster, hroller willplan for them to move to other nodes while the group is rebooted.This adds an option to also show this plan.
Spindles become part of htools resource spec
Spindles are now part of resource spec. Instances get created with spindlesspecified (which are just ignored when exclusive storage is disabled).

hroller: option to skip nodes with non-redundant instances
So far, hroller ignores the fact, that non-redundant instances exist.One option to deal is non-redundant instances is to not schedule thosenodes for reboot. This is supported by adding the option --skip-non-redundant....
Support online-maintenance in hroller
Make hroller take into account the nodes (redundant) instanceswill be migrated to. This be behavior can be overridden by the--offline-maintenance option which will make hroller plan underthe assumption that all instances will be shutdown before starting...
Add option --one-step-only to hroller
Add a new option to hroller to only output information about the firstreboot group. Together with the option --node-tags this allows for thefollowing work flow. First tag all nodes; then repeatedly compute thefirst node group, handle these nodes and remove the tags. In between...
Add option to hroller to select nodes based on tags
Add option --node-tags to tell hroller to consider only nodeswith these tags. A use case would be a tag tracking on whichnodes the maintenance has not yet been carried out, e.g., ifrolling reboots are interleaved with other cluster operations....
Make hroller insist on finding precisely one master node
As people rely on the master node being the last node of the lastgroup, make hroller fail, if no master node could be found in thecluster. This happens, e.g., if a backend format is used that does not...

Rename htools/ to src/
