Today we use `AbstractDisruptionTestCase` to test the behaviour of things like master elections in the presence of cluster disruptions. These tests have rather enthusiastic fault detection settings, detecting a fault if a single ping fails, with a one-second timeout. Furthermore there are some tests that assert the identity of the master remains unchanged during some disruption, and these assertions fail rather often thanks to the overly sensitive fault detector. However in a number of these tests the fault detector need not be this sensitive. This commit moves some such tests into their own test suite and uses more sensible fault-detection settings to avoid the kind of master instability that is causing CI failures. Closes elastic#37699
