rename db_schema in application.properties to db_name or db_database_name

[sheridancbio]

This property is to hold the name of the database which is being used to store data.

schema is a more general concept, as multiple databases can have identical schema.

In the mysql documentation, they use the pattern "db_name" to represent this string, for examples see:
https://dev.mysql.com/doc/refman/5.7/en/mysql.html
https://dev.mysql.com/doc/refman/5.7/en/alter-database.html
