in the admin actions extension.

remove-v3-xml-api has been approved.

Partially implements bp v3-api-admin-actions-split
DocImpact: Adds os-create-backup extension and moves the
create_backup functionality out of os-admin-actions into
this new extension.

xenapi plugins: Make sure subprocesses finish executing

Fixes bug 1286187

Neither execute_get_output() nor execute() would wait for the process to
fully finish executing. This could potentially create a race condition
where commands execute in a different order than intended.

Also, for execute() it could cause a process to never finish executing if
it generates enough output to block writing to the pipe.
