Add the ability to trigger a Quartz job on-demand through an Actuator endpoint

Before this commit, triggering a Quartz job on demand was not possible.
This commit introduces a new @WriteOperation endpoint at /actuator/quartz/jobs/{groupName}/{jobName}/trigger,
 allowing a job to be triggered by specifying the jobName,
 groupName, and an optional JobDataMap

+== Trigger Quartz Job On Demand
+
+To trigger a particular Quartz job, make a `POST` request to `/actuator/quartz/jobs/\{groupName}/\{jobName}/trigger`, as shown in the following curl-based example:
+
+include::partial$rest/actuator/quartz/trigger-job/curl-request.adoc[]
+
+The above example shows the triggering of the job, identified by the `samples` group and `jobOne` name, and with the specified `jobData`. The Quartz `jobData` is optional key-value data, that can be passed to the job when it's triggered.
+
+The response will look similar to the following:
+
+include::partial$rest/actuator/quartz/trigger-job/http-response.adoc[]
+
+
+[[quartz.trigger-job.request-structure]]
+=== Request Structure
+
+The request specifies an optional `jobData` associated with a particular job. The following table describes the structure of the request:
+
+[cols="2,1,3"]
+include::partial$rest/actuator/quartz/trigger-job/request-fields.adoc[]
