Previously, our conventions configured the source and target
compatibility on the project's JavaCompile tasks. This causes the
settings to be missed when importing the projects into Eclipse [1].

This commit updates the conventions to set the source and target
compatibility on the project-wide JavaPluginExtension. This allows
the Eclipse import to correctly detect and honour the settings.

Previously, the URI template handler installed by the client metrics
interceptor would always capture the URI template and push it onto the
deque, irrespective of whether auto timing was enabled. When
auto-timing is disabled the deque is never polled so this led to its
unrestricted growth.

This commit updates the URI template handler so that a URI template is
only pushed onto the deque when the auto timing configuration enables
the interceptor.

The auto-config requires Spring JDBC for DataSource creation from
spring.flyway.url or spring.liquibase.url, checking Flyway migrations
exist, etc. Without it, the application fails to start due to missing
spring-jdbc classes.

This commit updates the auto-config so that it backs off in the
absence of spring-jdbc.

Using the revision line means that the revision number is automatically
set. The revision number is then included by the HTML and PDF backends
in the standard location. In the HTML backend that's alongside the
list of authors. In the PDF backend that's on the title page.
