Stan Lagun 068831ccd8 Package versioning
With this change MuranoPackage becomes first-class DSL citizen.
Packages have version, runtime_version (that is specified
in Format attribute of the manifest file) and a list of classes.
Previously engine used to have package loader which had most
of "load" functionality and class loader that mostly acted as an
adapter from package loader to interface that DSL used to
get classes. Now class loader is gone and is replaced with
package loader at the DSL level. Package loader is responsible
for loading packages by either package or class name (as it was
before) plus semantic_version spec (for example ">=1.2,<2.0").
Package loader can now keep track of several versions of the same
package.

Also packages now have requirements with version specs.
All class names that are encountered in application code are
looked up within requirements only. As a consequence
packages that use other packages without referencing
them explicitly will become broken. An exception from this rule
is core library which is referenced automatically.

Partially implements: blueprint murano-versioning
