The `Tomcat.start()` has to happen to initialize the `ServletContext`
but we can immediately stop the connector and then restart it when
the context is finished refreshing. Seems to make curl fail quickly
if an app is slow to start.

Add license and legal information on third party open source software that is part of the CLI distribution

Correct the TravisCI link used for the build status image following the
GitHub organization rename from SpringSource to spring-projects.

* Add ability to detect spring-jms on the path and create a JmsTemplate with
  ActiveMQConnectionFactory
* Create tests showing autoconfigured JmsTemplate with ActiveMQ, but prove it
  backs off if a separate ConnectionFactory exists.
* Add support to spring-boot-cli to that it detects JmsTemplate, DefaultMessageListenerContainer,
  or SimpleMessageListenerContainer, and turns on autoconfiguration as well as
  add proper @Grab's and import statements.
* Write a jms.groovy test showing proper CLI support

Simplify ActiveMQ configuration

Update ActiveMQ to 5.7.0

username/password pairs were incorrect. The authentication manager has "user" and "password", so those credentials should be allowed to get the actual message.

* @EnableTransactionManagement triggers spring-tx imports
* Field or method of type JdbcTemplate or NamedParameterJdbcTemplate
  of DataSource triggers spring-jdbc imports

When user deploys app as a WAR in Tomcat, unless the tomcat-jdbc.jar
is in the app package, it will be found in the parent first and then
be unable to load the Driver class.

[Fixes #56720610] [bs-316] Tomcat non-embedded cannot load SQL driver class

[Fixes #56812760] [bs-319] Spring bootstrap in log message

Fix AuthenticationManagerBuilder code snippet to add the missing the
ObjectPostProcessor parameter for the constructor.

Issue: #45

Spring Data Mongo is the only dependency so it doesn't
really need a new starter. Added a sample though.

A side effect is that spring-boot-starter-data-jpa needs
to include an aspectjweaver depdendency. Hope that doesn't
hurt anything else.

[Fixes #56780004]

Add a Maven project to aggregate appropriate Javadocs into a
consolidated set.

Increase the timeouts to give CI builds more time should dependencies
be missing.

Remove sample gradle builds since they are not run during the regular
build and would need to be manually updated after a release.

In particular this allows a YAML externalization as an array
as opposed to a CSV.
