chore(deps): Make mysql-socket-factory-connector-j8 the explicit depe…

…ndency (#1983)

Update spring-cloud-gcp projects to depend explicitly on mysql-socket-factory-connector-j-8, instead of
relying on the central maven repo to replace dependencies on mysql-socket-factory with
mysql-socket-factory-connector-j-8.

This change should not have any effect on the classpath of existing customer applications. Customers
are already using mysql-socket-factory-connector-j-8 due to the relocation directive for the mysql-socket-factory
dependency.

MySQL Connector/J 5.0.x is no longer under development and has significant security vulnerabilities.
We strongly recommend all users update to 8.0.x instead. See the following GitHub issue for more details: GoogleCloudPlatform/cloud-sql-jdbc-socket-factory#1243

Fixes #1982
