Kyle Havlovitz eea2bd2753 Kill check processes after the timeout is reached (#3567)
* Kill check processes after the timeout is reached

Kill the subprocess spawned by a script check once the timeout is reached. Previously Consul just marked the check critical and left the subprocess around.

Fixes #3565.

* Set err to non-nil when timeout occurs

* Fix check timeout test

* Kill entire process subtree on check timeout

* Add a docs note about windows subprocess termination
