Configuring clients of a config server

To be able to get their configurations from the config server, our microservices need to be updated. This can be done through the following steps:

1. Add the spring-cloud-starter-config, and spring-retry dependencies to the Gradle build file, build.gradle.
2. Move the configuration file, application.yml, to the config repository and rename it to the name of the client as specified by the property, spring.application.name.

3. Add a file named bootstrap.yml to the src/main/resources folder. This file holds the configuration required to connect to the config server. Refer to the following for an explanation of its content.
4. Add credentials for accessing the config server to the Docker Compose files, for example, the product service:

product:
  environment:
 - CONFIG_SERVER_USR=${CONFIG_SERVER_USR}
 - CONFIG_SERVER_PWD...
