Support other payscales

Created by: abrahammartin

Current university payscales should only be used when CHRIS datamart returns "Grade XX" as "GRADE". Retrieve from CHRIS datamart a report with the distribution on how many different type of entries for "GRADE" are for current non ended contracts. If sufficient, support "Clinical (StR)" and "Clinical (SpR)", and "MRC Band XX".

Store a copy of the report in our PIDashboard Google Drive folder: "Technical Documentation"
