Need authorization support for Spring Cloud Config

[nsiniakevich]

Original implementation from spring has ability to add properties for authorization like username and password

Example bootstrap.yml

spring:
  cloud:
    config:
     uri: https://myconfig.mycompany.com
     username: user
     password: secret

doc

I tried to add the same properties to my micronaut bootstrap.yml config but got fail

I've checked SpringCloudConfigurationClient sources and I didn't find any username, password mention.

I have a http filter that i have been using to get around this limitation for some time now. I can contribute that as part of the repository if it makes sense.

The idea is that if the username and password properties are provided then activate the filter.

we probably need to improve this file: https://github.com/micronaut-projects/micronaut-discovery-client/blob/master/discovery-client/src/main/java/io/micronaut/discovery/spring/config/SpringCloudClientConfiguration.java
