428a60870a pruning: cleanup retention grid impl + tests + correct docs
package is now at 95% code coverage and the additional tests codify
all behavior specified in the docs

There is a slight change in behavior:
Intervals are now [duration) instead of (duration].
If the leftmost interval is not keep=all, the most recently created
snapshot will be destroyed if there are other snapshots within
that first interval.
Since we recommend keep=all all over the docs, and zrepl 0.3
will put holds on that snapshot if it is being replicated,
I feel like this is an acceptable change in behavior.

3a4e841c73 [#292] pruning: grid: add all snapshots that do not match the regex to the rule's destroy list
Before this patch, multiple grids with disjoint regexes would result in
no snapshots being destroyed at all.

d684302864 pruning: fix tests + implement 'not_replicated' and 'keep_regex' keep rule
tests expected that a KeepRule returns a *keep* list whereas it
actually returns a *destroy* list.
