* pull734:
  fixes gh-716 adds option to decode 404s

* pull663:
  Case insensitive Content-Encoding check

Fixes a problem with a header in the response containing
content-encoding in lowercase letters. Uses HttpHeaders for case
insensitve check.

Also fixes an issue checking if a request is made for gzip content.
If headers has more than gzip (ie gzip,deflate,sdch), checks if
contains gzip instead of equals to.

Fixes gh-662

* jkschneider-metrics-gauge-deconflict:
  Deconflict GaugeService provided by Servo/Spectator integration

Now uses spring-cloud-context NamedContextFactory.

see https://github.com/spring-cloud/spring-cloud-commons/issues/69

We need to use BeanFactoryUtils to search the context hierarchy
for custom instances.

Fixes gh-733

fixes gh-683

Add isDebugEnabled() for logging operations

If the management.port is explicitly set to something other than the
server.port, we can use it to set the status page and health URL
default values. (They can still be overridden by config properties.)

If management.port=0 there's not much we can do because we don't know
the port number yet when the instance config is created.

Fixes gh-425

The aspectjweaver jar includes all of aspectjrt, and the former is
used at runtime in a number of places (tests fail if you remove
it). Both are not needed so we have picked one (the other one than
recommended in gh-666).

Fixes gh-666
