This PR fixes #389,

Requirements:

• It is very important for this PR to work properly, specially with passing wf configs to ingest api, to use this PR from tool_opencast plugin Upgrade Opencast PHP Library to 1.8.0 + Api Version setting (OC 16 Support) + Moodle 4.4 Required Changes moodle-tool_opencast#63

• For this to work, opencast admin must make sure that the upload workflow is properly set and it has configuration panel elements!

Description

This PR is the feature request, by which teachers would have the ability to decide further upload process options provided in workflow configuration panel and set and pass them to the upload process.
In simple words, this PR provides the upload workflow configuration panels on the upload page to get user defined values, then pass those values to the workflow to process the uploaded video accordingly.

Settings

There are 2 new settings options added:

1. Show workflow configurations during upload (enableuploadwfconfigpanel) : This is the feature activation setting, by which admins could enable/disable this feature!
2. Allowed upload workflow configurations (alloweduploadwfconfigs) : With this setting, admins could set which config panel elements are allowed to be shown in the upload page, it is a comma-separated list of element ids.
   Leaving it empty means all elements would be shown!

Upload Page:

When all above mentioned requirements and settings are correctly set and configured, there will be a new section right after Event Visibility called Processing Settings in the upload page.
In this sections, every (allowed) element that is provided in the workflow config panel will be converted to moodle form element and shown to the teachers.

IMPORTANT TO KNOW (Standards):

• As of now the supported html elements are:
  • select
  • input (text)
  • input (checkbox)
  • input (radio)
  • input (datetime/date)
  • input (number)
• There is no possibility to support any inline JavaScript/JQuery code block!
• Each element must have an id attribute
• Each element should have a specific label element with attribute (for="{element-id}") containing the descriptive text (title) for the element.
  • If not provided, the system looks for the first preceding-forwarding sibiling label element
  • If any of the above are presented, the system will look for the first label element of the parent element.

Technical

This PR adds two new columns into block_opencast_uploadjob table:

• workflowconfiguration: This field contains the user defined (dynamic) workflow configuration values as JSON string.
• workflowid: This field contains the initial upload workflow id (retrievable only with ingest)
  Because of this two new addition this PR requires a plugin version increase, please be advised while testing this PR!
