This commit adds GC and thread jvm metrics to the existing memory
metrics. All three are now managed by a unique
management.metrics.binders.jvm.enabled property.
Closes gh-11425
This commit moves management.server.context-path to
management.server.servlet.context-path to align with the configuration
key for the application's main context path.
Closes gh-11359
`CorsEndpointProperties` lives in `endpoint.web.servlet` but is also used
in `endpoint.web.reactive`, so this PR moves it to its common parent
package.
This commit also extracts `CorsConfiguration` creation logic duplicated
in `WebMvcEndpointManagementContextConfiguration` and
`WebFluxEndpointManagementContextConfiguration` into
`CorsEndpointProperties`.

Change the default JSR-303 validator used by the configuration
properties binder so that it's initialized in a background thread.
This change allows the context to carry on loading additional beans
whilst the validator is initializing.
Fixes gh-11412
Update the `PropertyMapper` interface to return arrays rather than
Lists. Since implementations are package-private it's possible for us
to control how they are used and it helps to save a little memory.
Fixes gh-11411
Update the `LaunchedURLClassLoader` used for fat jar support so that
each iteration on a `findResources` result also allows for fast
exceptions.
Fixes gh-11406
Refactor fat jar loader classes so that less `char[]` instances are
created. This is primarily achieved by adding a new `StringSequence`
class that can chop up Strings without needing to copy the underlying
array. Since Java 8, calls to `String.subString(...)` always copy the
underlying char array. For many of the operations that we need, this
is unnecessary.
Fixes gh-11405
Remove support for the `__` environment variable list shortcut in order
to reduce complexity. The shortcut was developed before the new `Binder`
code was fully formed and isn't really necessary now since comma-lists
can be converted automatically.
Fixes gh-11410
