Elastic Configuration does not account for repo.search.url property

[GGoetzelmann]

Describe the bug

Using base-repo with search enabled and an ES instance not running under the default URL 'localhost:9200', but a different hostname or port number (configured in application.properties file), leads to
Error creating bean with name 'dataResourceController' due to org.springframework.dao.DataAccessResourceFailureException: Connection refused.

Meanwhile, the ElasticsearchUtil is quite satisfied (aka the ES service is running and reachable):

2024-11-18 16:27:56 2024-11-18T15:27:56.665Z TRACE 9 --- [           main] e.k.datamanager.util.ElasticSearchUtil   : Trying to connect to elasticsearch instance.
2024-11-18 16:27:56 2024-11-18T15:27:56.776Z TRACE 9 --- [           main] e.k.datamanager.util.ElasticSearchUtil   : Status code value: 200

To Reproduce
Steps to reproduce the behavior:

1. setup ES on non-9200 port or not-localhost
2. set repo.search.url to ES URL from step 1
3. enable search for base-repo
4. start application
5. See error

Expected behavior
Connection should be made to custom ES service

Likely culprit

https://github.com/kit-data-manager/base-repo/blob/main/src/main/java/edu/kit/datamanager/repo/configuration/ElasticConfiguration.java#L42

It seems to help to provide

    @Value("${repo.search.url}")
    private String searchUrl;

here, and to get host and port from there.
