Make Rapi backed set node tags correctly

Since the htools representation of a node now allows adding
the node tags, populate this field correctly in the Rapi
backend.

Extend the text format to contain node tags

In order to allow htools to make use of node tags, add them to the
text format. This is done by adding a new column at the end of the
node lines. If this column is missing, the default value (which
is the empty list) is left unchanged, thus yielding the current...

Extend the Node in the htools to allow adding node tags

Since hroller (and probably other tools in the future) will support
node selection based on node tags, extend the node data structure to
allow adding this information.

Make hroller filter the nodes before coloring the graph

Hroller used to first compute a coloring of the node graph and then
filter out the nodes that it had to work on. While the only filtering
was according to node groups this did not make a difference, as there...

Make mkNodeGraph ignore edges to non-present nodes

Change the behavior of mkNodeGraph to tacitly ignore all instances
where one of the nodes is not in the list of nodes. In this way, we
can construct sub-graphs by filtering the nodes and ignoring any
possibly added isolated nodes for the missing indexes....

hspace: Handle multiple ipolicy specs

With tiered allocation, hspace uses all the max specs in turn as the
initial instance spec.

Add multiple min/max specs in instance policy

Now instance policies can contain more than one min/max specs. This is the
main element of the "Constrained instance sizes" section in the
"Partitioned Ganeti" design doc.

This is a big patch, but changing the type of a configuration item requires...

Extend the simulation backend to also simulate a master node

In a simulated cluster as created by the simulation backend to
the htools, make the first node of the first node group the master
node. In this way, hools (like hroller) that require a master node...

Extend Text format by marking the master node

Sometimes, e.g., for hroller, it is necessary to know which node
is the master node. Therefore this information has to be included
in the text format as well. Since we never use an offline node as
master node, we can put this information can be put in the "is...
