chaos-monkey - improve include/exclude patterns

[raffaelespazzoli]

it is unclear what a pattern is and what type of expressions are supported. Please improve the documentation around it. ideally the patter should be a regexp. so mariadb-ha-[0-9] should match mariadb-ha-1 but not: mariadb-ha-1-build

based on my tests, the pattern supports the following mariadb-ha-*, which would match both of the above examples.

Also the chaos monkey implementation should be smart enough to not try to kill pods that are in complete state.

Thanks Raffaele
