This commit adds support for exposing endpoint operations over HTTP.
Jersey, Spring MVC, and WebFlux are all supported but the programming
model remains web framework agnostic. When using WebFlux, blocking
operations are automatically performed on a separate thread using
Reactor's scheduler support. Support for web-specific extensions is
provided via a new `@WebEndpointExtension` annotation.
Closes gh-7970
Closes gh-9946

This commit adds support to the new endpoint infrastructure for
exposing endpoint operations via JMX. It also introduces support for
JMX-specific extensions to a general-purpose endpoint. Such an
extension is identified by the `@JmxEndpointExtension` annotation.
See gh-9946
This commit introduces a new annotation-based programming model for
implementing endpoints. An endpoint is identified by a type-level
`@Endpoint` annotation. Method-level `@ReadOperation` and
`@WriteOperation` are used to identify methods on an endpoint class
that implement an operation and should be exposed (via JMX for
exmaple) to remote clients.

Update `ApplicationPid` to check POSIX file permissions in addition to
`File.canWrite()` before PID file. This helps to provided consistent
behavior, regardless of if the application is running as root or not.
Fixes gh-9922
This commit upgrades to the `maven-compiler-plugin` 3.6.2 that exposes
an additional property to enable the "-parameters" flag. This flag is
enabled for our own build and any project that uses
`spring-boot-starter-parent` as parent.
Closes gh-9323
This commit replaces the Acuator's support for hypermedia with a
single endpoint that returns HAL-formatted links to all of the
available endpoints. This is done without requiring Spring HATEOAS
to be on the classpath in a similar manner to the existing
CloudFoundry discovery endpoint.
Closes gh-9901
Unfortunately, creating the schema in code did not offer the right
condition to reproduce the error scenario. This commit restore the
initial intent, but separating the configuration and cleaning the
created context properly.
See gh-9862
This commit also makes sure to generate unique embedded data source and
disable datasource initialization as this is not required by those
tests.
See gh-9889
This commit adds an additional class check to AopAutoConfiguration as
it is main role is to configure `@EnableAspectJAutoProxy` which won't
work properly if `aspectjweaver` is not present.
Closes gh-9880
