Review Request for JMC-6587 - Tweaking IncreasingLiveSetRule

[Henrik Dafgård]

Hi everyone,

The rule that attempts to detect an increasing live set is currently a bit
too eager to find a result, even when there are too few collections to make
a meaningful calculation of any increase in the live set. It can also give
a fairly high severity result even without any old collections occurring at
all, which can be quite misleading, as without old collections we can't
really say whether or not the live set itself is increasing.

I made a few small tweaks to the rule, as well as adding a configuration
value to allow end-user tweaking as well, to help alleviate this.
