* Consolidates and renames the runtime used as a base for all the others:
* Before: `xmodule.x_module:DescriptorSystem` and
`xmodule.mako_block:MakoDescriptorSystem`.
* After: `xmodule.x_module:ModuleStoreRuntime`.
* Co-locates and renames the runtimes for importing course OLX:
* Before: `xmodule.x_module:XMLParsingSystem` and
`xmodule.modulestore.xml:ImportSystem`.
* After: `xmodule.modulestore.xml:XMLParsingModuleStoreRuntime` and
`xmodule.modulestore.xml:XMLImportingModuleStoreRuntime`.
* Note: I would have liked to consolidate these, but it would have
involved nontrivial test refactoring.
* Renames the stub Old Mongo runtime:
* Before: `xmodule.modulestore.mongo.base:CachingDescriptorSystem`.
* After: `xmodule.modulestore.mongo.base:OldModuleStoreRuntime`.
* Renames the Split Mongo runtime, the which is what runs courses in LMS and CMS:
* Before: `xmodule.modulestore.split_mongo.caching_descriptor_system:CachingDescriptorSystem`.
* After: `xmodule.modulestore.split_mongo.runtime:SplitModuleStoreRuntime`.
* Renames some of the dummy runtimes used only in unit tests.
This function was only used by tests. It was breaking tests from the `xmodule`
package on the devstack because the dist.key of its entry_points is `open-edx`.
- Moving xmodule folder to root as we're dissolving sub-projects of common folder in edx-platform
- More info: https://openedx.atlassian.net/browse/BOM-2579
- -e common/lib/xmodule has been removed from the requirements as xmodule has itself become the part of edx-platform and not being installed through requirements
- The test files common/lib/xmodule/test_files/ have been removed as they are not being used anymore
