Kirill Zaitsev 08f5193eae Allow package cache to persist on disc
Changes APIPackageLoader class, to enable it to persist downloaded
packages on disc. Adds synchronization between eventlet threads and
different murano-engine workers, since it's now possible for
several engines to attempt to download the same package
The functionality is controlled with 'enable_package_cache' conf
variable.

Targets blueprint: murano-engine-package-cache
