XD-1153 Use Native Tail Adapter in Test Fixture

Test fixture used 'end="false"' instead of 'lines=+0'.

Adding the 'end' option inadvertently caused the Apache Tailer
to be used.

Change the test fixture to use the native adapter.

Add new properties to the tail source to allow complete control
over which adapter is used. Using the Apache adapter requires
setting `native-options=''` together with one or more of the
Apache properties (delay, fromEnd, reOpen), to use the Apache
adapter.

Use a POJO for ModuleOptions
XD-1103: Reinstate JDBC sink DataSource

Since the big Bootification the jdbc sink has been sharing
a DataSource with the parent context. This change re-instates
the local version (using Boot features).

Also resets initializeDatabase to default to true which was the
cause of the original issue.
Reinstate rabbit module connection factories

Similar to the JDBC sink datasource, bootification original removed
these. This commit adds the individual module configurations back.
