Fix encrypted backup column issue for sub-2014

This makes a few changes
1. Populates version and edition variables
2. Only checks for encrypted backups on 2014+
3. Adds dynamic SQL to the table/index creation section of the data
mover to add the column encryptor_type to the repo table if it doesn't
already exist
4. Adjusts dynamic SQL for insert to the repo to use a CASE expression
based on version number to either append encryptor_type or skip it to
the column list (both insert and select)
