Report to New Relic certain per-request details about the
DjangoXBlockUserStateClient.  The following metrics are reported for the
get_many() call:

xb_user_state.get_many.calls
xb_user_state.get_many.duration
xb_user_state.get_many.blocks_requested
xb_user_state.get_many.blocks_out
xb_user_state.get_many.size
xb_user_state.get_many.<block_type>.blocks_requested
xb_user_state.get_many.<block_type>.blocks_out
xb_user_state.get_many.<block_type>.size

Similarly, for the set_many() call:

xb_user_state.set_many.calls
xb_user_state.set_many.duration
xb_user_state.set_many.blocks_created
xb_user_state.set_many.blocks_updated
xb_user_state.set_many.size
xb_user_state.set_many.<block_type>.blocks_created
xb_user_state.set_many.<block_type>.blocks_updated
xb_user_state.set_many.<block_type>.size

Where <block_type> is one of "chapter", "course", "problem", "video",
etc.

PERF-354

Use this middleware and its helpers to accumulate custom New Relic
metrics on a per-request basis.  If, while handling a request, the app
does not accumulate any metrics, this middleware is a very lightweight
no-op.

This commit also enables the middleware!

MA-333 Added ability to refresh uploaded videos

This adds ability to refresh the list of uploaded videos without refreshing the whole page.

Added a refresh button that when clicked:
- fetches a fresh list of uploaded files from the server
- updates `PreviousVideoUploadListView`
- removes the successfully completed uploads from `ActiveVideoUploadListView`
- retains the ongoing or failed uploads in `ActiveVideoUploadListView` so that they can be monitored/retried

The view can also be refreshed without user action, but I felt it may be less surprising to have a button instead.

MA-333 update: auto-refresh list, fix test failure

Changes:
1. Refresh of file list triggered by upload completion. Refresh button retained and label changed to "Refresh List".
2. Added `aria-live="polite"` to `.active-video-upload-list` and `.assets-table`.
3. Removed unused parameter `evt`.
4. Added self to the `AUTHORS` file.
