Previously, all attempts to log a configuration file were logged at DEBUG
level which lead to a lot of noise as Spring Boot looks in many places by
default.
We now only log the files that are effectively found at DEBUG level and
all failed attempts at TRACE level.

If a `JavaMailSenderImpl` is available, check that the underlying mail
server is available on startup. Add a `spring.mail.test-connection`
property to control this behaviour.

If spring-hateoas is on the classpath and an MvcEndpoint returns a
@ResponseBody it will be extended and wrapped into a Resource with links.
All the existing endpoints that return sensible JSON data can be extended
this way (i.e. not /logfile). The HAL browser will also be added as an
endpoint if available on the classpath. Finally, asciidocs for the
Actuator endpoints are available as a separate jar file, which if
included in an app will also generate a new (HTTP) endpoint.
Fixes gh-1390
There is a new spring.factories entry for
org.springframework.boot.actuate.autoconfigure.EndpointWebMvcConfiguration
which loads extra beans into the MVC config for the Actuator.
If the management context is a child context all the beans go in the
child (except the Spring Security filter still). A big bonus is that
you can add WebConfigurerAdapters to configure static resources etc.
A new component called ManagementContextResolver can be used to
locate the ApplicationContext for the MVC endpoints.

This commit improves support of the Resource Handling features
introduced in Spring Framework 4.1. Those features add new ways to
resolve and transform static resources in applications.
See [this blog
post](https://spring.io/blog/2014/07/24/spring-framework-4-1-handling-static-web-resources)
for more details.
The `ResourceUrlEncodinFilter` is added for compatible template engines:
Velocity and Thymeleaf. It assists them with rewriting the URLs of
static resources when rendering templates.
New keys are added in the `ResourceProperties` in order to configure
the Resource Handling chain. `ResourceResolvers` and
`ResourceTransformers` are registered accordingly in
`WebMvcAutoConfiguration`.
Here is an example of enabling a `ContentVersionStrategy` on all
static resources, meaning their names will be changed for cache
busting purposes by adding a content hash at the end of the file name.
Like "/js/jquery.js -> /js/jquery-872ca6a9fdda9e2c1516a84cff5c3bc6.js".
```
spring.resources.chain.enabled:true
spring.resources.chain.strategy.content.enabled:true
spring.resources.chain.strategy.content.paths:/**
```

Improve the "hints" section of the metadata so that each hint can provide
the reference to a value provider.
A value provider defines how a tool can discover the potential values of
a property based on the context. The provider is identifed by a name and
may have an arbitrary number of parameters.
Closes gh-3303
Update documentation section that discusses uber jars since it conflates
the concepts of the uber jar and the shading of dependencies into jars
(which may or may not be true uber jars).
Fixes gh-3321
Create a new section in the meta-data called "hints" where users can
provide hints about a given property. The most basic use case for now
is to provide a list of values that a property can have. Each value may
have a description.
This sample JSON provides a basic example for a property called `foo.mode`
that exposes 3 values: "auto", "basic" and "advanced".
```
"hints": [
{
"id": "foo.mode",
"values": [
{
"value": "auto",
"description": "Some smart description."
},
{
"name": "basic"
},
{
"name": "advanced"
}
]
}
]
```
This information can be read by tools (such as IDE) and offer an
auto-completion with the list of values.
Closes gh-2054
Add AnsiPropertySource which allows named ANSI codes to be resolved
and update ResourceBanner to include it.
This commit also deprecates constants defined in AnsiElement and
replaces them with AnsiStyle, AnsiColor and AnsiBackground enums.
Closes gh-2704
These files are modified by Eclipse for some reason when you change files
like Thymeleaf HTML files. `META-INF/maven/**` has been added to the
default exclusion.
Closes gh-3295
Closes gh-3297
Update `ApplicationPidFileWriter` to support a 'fail on write error'
properties which allows the user to exit the application if the PID
file cannot be written.
This commit also deprecates `spring.pidfile` in favor of
`spring.pid.file` so that the new property can be added without overlap.
Fixes gh-2764
