Add operation task-id-lookup operation to qseow-task node

[mountaindude]

Input message could look something like this:

msg.payload

"taskName": [],
"tagName": []

Output would be arrays of task IDs and objects for all matching tasks.
All kinds of tasks should be handled (reload, external program etc).

msg.payload

"taskId": [],
"taskObj": []

The taskObj array will contain full task objects for the tasks matching the search criteria in the input message.
