Cache tracker is a thread-local global object that indirectly depends on
the lifetimes of other objects. In particular, a member of
cache_tracker: mutation_cleaner may extend the lifetime of a
mutation_partition until the cleaner is destroyed. The
mutation_partition itself depends on LSA migrators which are
thread-local objects. Since, there is no direct dependency between
LSA-migrators and cache_tracker it is not guarantee that the former
won't be destroyed before the latter. The easiest (barring some unit
tests that repeat the same code several billion times) solution is to
stop using globals.
This series also improves the part of LSA sanitiser that deals with
migrators.
Fixes#3526.
Tests: unit(release)
