Update the `spring-boot`, `spring-boot-autoconfigure` and
`spring-boot-actuator` project to generate configuration meta-data
files during compilation.

This commit adds an abstraction that provides a standard manner to
retrieve various metadata that are shared by most data sources.
DataSourceMetadata is implemented by the three data source
implementations that boot supports out-of-the-box: Tomcat, Hikari and
Commons dbcp.
This abstraction is used to provide two additional metrics per data
source defined in the application: the number of allocated
connection(s) (.active) and the current usage of the connection pool
(.usage).
All such metrics share the 'datasource.' prefix. The prefix is further
qualified for each data source:
* If the data source is the primary data source (that is either the
only available data source or the one flagged @Primary amongst the
existing ones), the prefix is "datasource.primary"
* If the data source bean name ends with "dataSource", the prefix is
the name of the bean without it (i.e. batchDataSource becomes batch)
* In all other cases, the name of the bean is used
It is possible to override part or all of those defaults by
registering a bean with a customized version of
DataSourcePublicMetrics.
Additional DataSourceMetadata implementations for other data source
types can be added very easily, check
DataourceMetadataProvidersConfiguration for more details.
Fixes gh-1013
Refactored HealthEndpoint to be able to take multiple HealthIndicators. Extracted configuration of HealthIndicators out of EndpointAutoConfiguration and added new HealthIndicatorAutoConfiguration class.
Added HealthIndicators for Redis and Mongo.
This commit harmonizes the dependency management of internal modules
so that versions can be omitted everywhere. Update the maven coordinates
to provide the full groupId for consistency
Two modules are still relying on the spring-boot test-jar but it was
not generated anymore. Adding the generation of test-jar again as
a workaround until we completely removes the use of it.
Salvatore has indicated that Jedis is his Java Redis client of choice.
This commit updates the auto-configuration support, actuator and
Redis starter accordingly.
Completes #745
Upgrade to Tomcat 7.0.50, working around the potential
NullPointerException by also adding dependencies to
tomcat-embedded-jasper (which is now also required for Hibernate
Validator 5.0, see commit 377953babd)
Fixes gh-245
