Previously, there were two problems with servlet context initializer
beans that are a scoped proxy:
1. When there's no explicit registration bean the target of the scoped
proxy is registered rather than the proxy. This meant that the
proxy had no effect as it was being bypassed.
2. When there is an explicit registration bean, the registration is
performed twice: the faulty implicit registration described above
and explicit registration.
A fix (SPR-14816) has been made in Spring Framework so that we can
correctly determine the type of bean that will be produced by a
scoped proxy's factory bean. That change, coupled with the change in
this commit that ignored beans that are the target of a scoped proxy
addresses both of the problems described above. A single registration
is now performed and its the scoped proxy, rather than its target,
that is registered.

Update `DevToolsPropertyDefaultsPostProcessor` so that property defaults
are only added at development time. Properties are now added only when
`Restarter` is initialize or remote devtools is enabled.
Fixes gh-7014
Update `ApplicationPidFileWriter` to support `ApplicationReadyEvent` in
addition to the already supported `ApplicationEnvironmentPreparedEvent`
and `ApplicationPreparedEvent` events.
Closes gh-7066
Fixes gh-7027
Update JpaBaseConfiguration so that the persistenceUnitRootLocation is
no longer detected. The update to gh-7003 means that we can now rely on
the standard detection mechanism.

Previously, if Boot's JarURLConnection pointed to the root of a nested
entry, e.g. /BOOT-INF/classes, a call to getInputStream() would throw
an IOException. This behavior is reasonable for a URL that points
to the root of a normal jar as the jar itself is on the class path
anyway. However, for a nested jar it meant that a call to
ClassLoader.getResources("") would not include URLs for any nested
jars and directories (/BOOT-INF/classes and jars in /BOOT-INF/lib).
This is due to some logic in URLClassPath.Loader.findResource that
verifies a URL by opening a connection and calling getInputStream().
The result of missing URLs for the root of nested jars and directories
is that classpath scanning that scans from the root (not a good idea
for performance reasons, but something that we should support) would
not find entries in /BOOT-INF/classes or in jars in /BOOT-INF/lib.
This commit updates our JarURLConnection so that it no longer throws
an IOException when asked for an InputStream for the root of a nested
entry (directory or jar).
Fixes gh-7003
Previously, if an auto-configuration class was (wrongly) located in a
candidate package for component scanning, the class was silently loaded
as an app configuration (i.e. with the wrong lifecycle).
This commit adds an `AutoConfigurationExcludeFilter` to
`@SpringBootApplication` so that such classes are automatically
filtered. Since they are registered in `spring.factories`, we can
silently ignore them since we know they'll be loaded later on.
Closes gh-7168
