* Add connection properties to specify a custom TrustManager

Adds two new connection properties that can be used to specify a custom
TrustManager implementation:

trustManagerClass - Class name of the custom TrustManager

trustManagerConstructorArg - Optional argument to pass to the constructor
constructor of the custom TrustManager.

If encryption is enabled and the trustManagerClass property is specified,
it will be retrieved via Class.forName(...).

If the optional property trustManagerConstructorArg is specified, then a
constructor will be retrieved via getDeclaredConstructors(String.class).
The TrustManager will then be instantiated by specified the optional
argument as a parameter.

If the optional property trustManagerConstructorArg is not specfied,
then the default no argument constructor of the class will be retrieved
and instantiated.

* Adding a few simple test to verify the newly added connection properties

* Rename custom trustmanager test package name

Previous package name used camel case. Corrects naming to be lower case.

* Add missing newlines to trustmanager test classes

* Refactor references to trust managers in tests

* Refactor whitespace and unneeded extends Object

* Add resource cleanup to trust manager tests

* Refactor failure handling for trust manager test

* Rename tmClazz to tmClass

* Add new trust manager properties to SQLServerDataSource

* Reword comment

* Format custom trustmanager changes with auto formatter
