Reserve ecommerce worker username

Django's user model allows email addresses to be blank. However, edx-platform includes a migration requiring that email addresses be unique. Someone in our production environment already had a blank email address, so this migration was failing earlier.

MA-1416 image mimetype uploads

CourseOverview will only delete old versions of saved data.

update testing.rst

This will allow v1 code of CourseOverview to delete entries. While
this is not a good thing in general (and future versions will ignore
entries with higher versions than they support), this is necessary
to prevent errors with the existing code in a rollback situation.
Otherwise, old code trying to delete CourseOverview entries will
fail with a foreign key constraint violation.

Previously, CourseOverview would delete data for any version
that didn't match the current one. That could cause problems
during deploys, when multiple versions of CourseOverview
were active. They would overwrite each other, and that could
cause problems if the old one overwrote the new one -- in
our case, the new one created a new table with foreign key
links that the old one was unaware of, and trying to delete
it would have caused an error.

Implement a Studio tab plugin manager, define a namespace for Studio tab plugins, and introduce an abstract base class used to represent Studio tabs. This does not introduce changes required to inject such plugins into the Studio UI. ECOM-2187.
