Rename some helper functions for consistency

This changes the names for some helper functions so that future
patches are touching less unrelated code. The change replaces
shortened prefixes with the full type name.

separate module that doesn't have any other dependencies.

Change how node pairs are generated/used

Currently, the node pairs used for allocation are a simple [(primary,
secondary)] list of tuples, as this is how they were used before the

primary node, and we have to unpack this list right after generation....

Parallelise instance allocation/capacity computation

This patch finally enables parallelisation in instance placement.

My original try for enabling this didn't work well, but it took a
while (and liberal use of threadscope) to understand why. The attempt...
