When the config server is located via discovery
(spring.cloud.config.discovery.enabled=true) the discovery process
should attempt to establish whether the config server prefers to
be accessed securely (e.g. it registered with Eureka as
nonSecurePortEnabled=false). This change ensures that this happens.

Fixes gh-450

This test made wrong assumptions about the content of the child
context when trying to simulate autoconfiguration. It needed
an extra EurekaClientAutoConfiguration.

This version of Eureka is a bit of a singleton pig, so it's hard
to control the lifecycle, but this seems to work for all the tests
and also the eureka-first and ribbon-eureka samples.

The flag has always been there, it just isn't carried through to the ribbon client configuration
without this change if I understand this change correctly.

Fixes gh-315, fixes gh-423.
