Refactors and reworks the LibraryContentBlock so that its
sync-from-library operations are asynchronous and work with
V2 content libraries. This also required us to make
library_content block duplication asynchronous, as that
involves syncing from the source library.
For the sake of clarity, this PR includes two major method renames:
* update_children(...) -> sync_from_library(...)
* refresh_library(...) -> sync_from_library(upgrade_to_latest=True, ...)
an an XBlock HTTP handler rename:
/refresh_children -> /upgrade_and_sync
There are still a couple issues with import or duplication
of library_content blocks referencing V2 libraries other than
latest. These will be resolved in an upcoming PR.

This PR adds a management command to, given a mapping of V1 content libraries to matching v2 content libraries, replaces references to v1 libs in courses (in library source xblocks) with V2 libraries. It does so by manipulating the mongo document directly.
it also offers some improvements to the management command which copies all v1 libraries into v2 libraries.
-> bind_for_student() and friends change the user_id

This makes a couple of changes to the xblock handler in the CMS. These changes
add a handful of utility functions and modify the existing ones to make reuse
of existing blocks easier. With these changes, it is possible to copy an
entire section from one course to another, and then later refresh that section,
and all of its children, without destroying the blocks next to it.
The existing _duplicate_block function was modified to have a shallow keyword
to avoid copying children, and the update_from_source function was added to
make it easy to copy attributes over from one block to another. These functions
can be used alongside copy_from_template in the modulestore to copy over blocks
and their children without requiring them to be within any particular container
(other than a library or course root)-- thus allowing library-like inclusion
without the library content block. This is especially useful for cases like
copying sections rather than unit content.

- V2 libraries are available for selection in the Random Block edit modal;
- selected V2 library blocks are copied to the modulestore and saved as children of the Random Block;
- V2 library version validation works the same as for the V1 libraries (with possibility to update block with the latest version);
- filtering by problem type can't be done for V2 the same as for V1 because the v2 library problems are not divided by types;
- the problem type field is hidden for v2 libraries in the edit mode;
- unit tests added/updated.
We have found that for many courses on edx.org, the "current version"
of the course that's stored in MongoDB doesn't match what's stored in
MySQL. Although this doesn't directly cause any problems as the
"current version" (course index) is not normally read from MongoDB,
it's not supposed to happen - and it can cause problems if some other
extra-platform components (like a pruner script) read the course
indexes out of MongoDB.
We still aren't sure what can cause MongoDB and MySQL to get out of
sync in the first place; this won't necessarily fix that issue. What
this does fix is a bug that seems to be: once they get out of sync,
they stay out of sync and mongo will stop receiving writes.
The Mongo code in most cases will only write a new record if the
"current" record's last_update matches the last_update value before
the change was made. e.g. last_update is "10am", user makes a change,
Mongo gets updated only if the current row's last_update is still
"10am". Otherwise it's considered a "collision" and silently ignored.
Once Mongo and MySQL somehow become out of sync, they may stay out of
sync because any new writes will have a last_update value read from
MySQL, which is newer than the value in MongoDB, so the MongoDB writes
will all be rejected as "collisions".
This should fix the issue by making mongo writes always match the MySQL
writes, instead of letting the Mongo code "decide on its own" when to
write course index updates or not.

- -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
