Moved fields and forms to scheduler base solution.

The scripts on the Teams Integration have been incorporated into tpg_ppplibrary_js for Scheduler. For PfW the scripts have been moved to the base solution.

Post upgrade step: Add the field tpg_teamsintegrationisavailable to your project form.

The scripts will check for a field called tpg_teamsintegrationisavailable, which should be added to the Project form. The field will be set to true or false depending on if the script can find a value in the tpg_CreateTeamHTTPTriggerFlowUrl environment variable. The Teams buttons will hide or show depending on the value tpg_teamsintegrationisavailable.
