For some reason the exception mappings are only created with the
publisher is initialized in the constructor of DefaultAuthenticationEventPublisher.
Changed SpringBootWebSecurityConfiguration to do that rather then
relying on the ApplicationEventPublisherAware behaviour to inject it.

Fixes gh-719

The username/password option stil lonly works for a single host (to
connect to a cluster I suspect you need to set the URI). Also added
a MongoClientOptions (if a bean of that type exists it will be
used to populate the options that aren't in the URI).

Prior to this commit, a JmsTemplate bean created automatically by Boot
had its "pubSubDomain" flag enabled. It's far more usual to fallback on
queue rather than topic.

This commit flips the default value of the configuration property.

Fixes gh-626

The dependencies pom.xml now declares an import to the spring-data-releasetrain BOM pom.xml which in turn constraints version numbers for a dedicated release train release. This has the effect of users being able to upgrade to a certain release train by redeclaring the spring-data-releasetrain.version property to e.g. Dijkstra-M1. Individual modules can be upgraded by simply declaring the dependency in the desired version manually in a <dependencies /> or <dependencyManagement /> block.

Removed the explicit declaration for Spring HATEOAS as it is pulled in transitively by Spring Data REST anyway and thus makes sure it's in a compatible version.

* dep-mgt:
  Add spring-boot-autoconfigure to starter parent

Fixes gh-728

If Spring HATEOAS is on the class path, then @EnableHypermediaSupport
