Introducing Performance Loggers

[machavan]

Description:

This is a foundational change for introducing performance loggers which can be used tracking performance of various activities within the mssql-jdbc driver e.g. connection time, login time, token acquisition time etc.

A new java.util.Logging logger com.microsoft.sqlserver.jdbc.PerformanceMetrics.Connection is introduced here which can be subscribed to by applications.
More loggers such as com.microsoft.sqlserver.jdbc.PerformanceMetrics.Statement will be introduced in future.

Various performance activities to be tracked are defined in a PerformanceActivity Enum which will be amended with new additions in future.

Testing:
-Manual testing of new logger functionality.
-All existing tests ensure testing of newly added code.
