Some weird looking test failures led me to track this down.
If the user changes the prefix for metric names, he probably wanted
to change the keys as welll (otherwise 2 repositories can use the
same key, which is why the test was failing for me). We can do that
in an afterPropertiesSet().
If the actuator endpoints are configured on a different port then there
are some settings in the main ServerProperties that we would like to
re-use (e.g. the access log). The easiest way to do that is to just
configure the management server using the same ServerProperties instance
and then overwrite the things that are different (and stored in
ManagementServerProperties).

Done in order to align with the rest of the configuration. Absent this
check, the bean will be installed in non-web applications without the
corresponding dependencies, causing the bootstrap to fail.
Closes gh-1588
This is a continuation of the changes made in 611f978. It makes some
more @Bean methods public and adds tests to spring-boot-actuator and
spring-boot-autoconfigure to prevent against non-public methods being
introduced in the future

When MVC path matchers are used as metric keys, they can still contain
invalid characters and patterns (like asterisks). This change removes
some more special characters and also tidies up the names a bit so
no key part starts or ends with "-" (which is ugly).
Fixes gh-1528
Protecting /error doesn't make a great deal of sense and if it is
protected you don't get the ErrorPageFilter for the attempt at loading
it, so Tomcat renders its own HTML error page (when deployed as WAR).

Import DataSourcePoolMetadataProvidersConfiguration from
DataSourceAutoConfiguration so that PoolMetadataProviders are configured
even if actuator is not used.
This commit improves DataSourceMetadata to expose the validation
query. This can be used by DataSourceHealthIndicator as the query
to use instead of "guessing" which query could be applied according
to the database type.
Fixes gh-1282
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.
