Update SolrHealthIndicator to extend AbstractHealthIndicator
Upgrade to Spring Batch 3.0.0.RELEASE

Closes #906

Continue to support spring.jpa.hibernate.namingstrategy

In 1.0, the property spring.jpa.hibernate.namingstrategy could be
used to configure Hibernate's naming strategy. This was at odds with
most other configuration where binding to namingStrategy would require
a property with some indication that it was two separate words, for
example: naming-strategy, naming_strategy, or namingStrategy

This commit adds a new setter, setNamingstrategy, to JpaProperties so
that an app that was using namingstrategy in 1.0 continues to work
in 1.1.

Add servlet path to /error if it is customized

In addition I added some convenience methods to ServerProperties
(servletMapping() and servletPrefix()) for manipulating the
servlet path as provided by the user (e.g. normalizing it into
a valid Servlet mapping path for the DispatcherServlet).

Fixes gh-939, see also gh-936

Update Health and Status objects to be immutable, update the existing

Dont’t auto-configure FreeMarker and Velocity without context-support

Boot’s auto-configuration for FreeMarker and Velocity relies on Spring’s
support for them that’s packaged in spring-context-support. Only
auto-configure them if their respective Spring classes are on the
classpath
