Needed in `EurekaClientConfigBean` because `CloudEurekaTransportConfig` is a separate class.

Fixes a race condition introduced in 1.3.0

Ribbon client configuration based on Eureka is disabled if eureka.client.enabed is set to false.

Fixes gh-335

Make EurekaDiscoveryClient.EurekaServiceInstance constructor public

prefer-ip-address does not work in statusPageUrlPath when management port != server port

This change gets `prefer-ip-address` via a relaxed property resolver to set the value during the creation of the `EurekaInstanceConfigBean`.

s-c-commons creates an AutoServiceRegistrationProperties bean if enabled.

This commit only auto registers with eureka if that bean is available.

Defaults were set too late and were overriding values set in the environment.

Specifically, spring.application.name took precedence over eureka.instance.appname.

 fixes gh-1516

Specifically, add `@ConditionalOnBean(EurekaClient.class)`.

Fixes an issue where eureka and ribbon are on the classpath, eureka.client.enabled=false which would cause a bean not found exception.

fixes gh-1511

(cherry picked from commit d1f8c031)

Use the new ServiceRegistry interface

Creates a new EurekaRegistration object that aggregates classes needed
for a single registration.

Use statusPage/healthCheckUrlPath w/ custom management.port

Added RelaxedPropertyResolver to handle multiple valid formats for
eureka properties.  Added tests.

Fixes gh-1348

Was previously milliseconds/seconds when calculating whether to display the message about reporting failures.

This fixes a case where the ribbon property is set `ribbon.IsSecure=false`, but because the eureka secure port was enabled, the uri created by ribbon was prefixed with https when it shouldn't have.

All places where isSecure is need have been consolidated into RibbonUtils.

A problem in Spring Boot means that the extra conditions are combined
with OR not AND, so it's a bug to have more than one until that
gets fixed (in an AnyNestedCondition).

See https://github.com/spring-projects/spring-boot/pull/6672

Allows ribbon class name properties to be used to define beans.

This seems like boilerplate, but works, though not easily extensible.

fixes gh-927

Eliminates a legacy use of a static singleton. This will help allow multiple registrations.

fixes gh-1051

Before this change we were seeing test failures in
spring-cloud-netflix-eureka-server (but only with Spring Boot 1.4)
caused by annotation processing explosion when
RefreshScopeAutoConfiguration is not on the classpath.

The zone for a remote server comes from its
eureka.instance.metadataMap.zone, but we didn't (until this change)
apply the same logic to the client. If the client is registering
itslef with eureka then it will have a metadataMap itself and
we should be able to just reverse the logic.

Fixes gh-991

Makes use of StringUtils.commaDelimitedListToStringArray

Fixes gh-980

This change requires setting `ribbon.http.client.enabled=true`.

This change addresses issue #648 Getting Retry Working In RestTemplate. There is also a fix in place that addresses the issue #357 RestTemplate Error.

https://github.com/Netflix/eureka/releases/tag/v1.4.5

restores http basic auth.

Fixes gh-642

Latest Eureka from Netflix uses a different HTTP client, and it
ignores the HTTP basic credentials in a service URL. This change
partially restores the old behaviour by providing an interceptor
(ClientFilter) that has a single, global username/password
taken from the first serviceUrl that contains credentials.

Fixes gh-849

Eureka now has the option (maybe always there) to not register
and that's a sensible default in the bootstrap phase (when we
might not know the port yet).

See corresponding change in s-c-commons https://github.com/spring-cloud/spring-cloud-commons/commit/539a537abba58ed2261c4485d7f9426d2aa57453
