This commit ensures that `setLogLevel` on the `LoggingSystem` accepts
a `null` level. A `null` level means any customization sets on that
level should be removed and the default configuration should be used
instead.

Effectively, the level of the parent logger is going to be used when
`setLevel` is called with `null` for a given logger.

Most JMX clients do not accept to pass `null` for an argument so an
empty String is translated to null in that specific case.

Calling launch of PropertiesLauncherTests sets the thread context
class loader to an instance of LaunchedURLClassLoader. To avoid this
class loader being used beyond the scope of the test and launcher
that created it, this commit updates PropertiesLauncherTests to
capture the TCCL before each test and restore it after each test.

Previously, Spring Boot's Gradle plugin provided custom software
components (bootJava and bootWeb) for publishing the artifacts created
by the standard bootJar and bootWar tasks respectively. Providing a
custom software component requires the usage of some of Gradle's
internal APIs and this has now proven to be more trouble than it is
worth.

This commit removes the custom software component and documents how
to publish the artifact created by a BootJar or BootWar task directly
instead.

Usages has been removed in Gradle 4.0 and replaced with the use of
a new ObjectFactory API that can be used to create a Usage. This
commit uses reflection to access the ObjectFactory from the Project
and use it to create a Usage when an attempt to use Usages fails.
