implemented sticky options for PM

implemented sticky options for PM. It allows to have options stick for
PM when used across different thread. Previous implementation used
ThreadLocal, so options were valid only in the Thread scope.
The new implementation gives control when setting options to make them
sticky (global scope) or not (thread scope).
refactored unit test to centralize the AWS property file.
