This adds the soft shutdown feature for coordinators for the 3.8
branch (backport from devel).
Here is the design document:
https://github.com/arangodb/documents/blob/master/DesignDocuments/03_IN_PROGRESS/SoftShutdownCoordinators.md
The basic idea is to allow to put a coordinator into a "soft shutdown
mode" in which it finishes ongoing work but does no longer accept
new work. This should make restarting or upgrading coordinators less
intrusive for clients.
To be merged for 3.8.1, together with #14435
