Bulk closing of alarms through UIMAPI

Issue/Introduction

Have a need for bulk closing of alarms with given nimids, initiated by a program based on user input.
This action needs to be performed within a reasonable amount of time, and we need to indicate to the user if the action failed.

 Have attempted using the UIMAPI (PUT /uimapi/alarms/<nimid>/ack) for this, but ran into several problems:

1.  Closing multiple alarms requires multiple requests;
2.  It takes a long time (about 0.4 seconds per alarm), even if all of the requests are sent at once (the duration of each request scales with the number of requests);
3.  When closing a large number of alarms (starting at ~200), the API does not seem to respond (we gave up after several hours); and
4.  When a request in cancelled, it frequently causes subsequent alarm related requests to hang, requiring a restart to the ems probe.
