Add support of mTLS in Spring Cloud Config Client

[ishumov]

Describe the bug

I'd like to use Spring Cloud Config Client to connect to our Spring Cloud Config Server using mTLS. But after providing corresponding truststore.ks an keystore.ks in spring-cloud-config section I figured out that keystore.ks is used as a parameter for webClientOptions.setTrustStoreOptions instead of webClientOptions.setKeyStoreOptions. So no client certs could be sent to server. From my point of view current behavior looks like a bug.

Expected behavior

keystore.ks used as a parameter for webClientOptions.setKeyStoreOptions

Actual behavior

keystore.ks used as a parameter for webClientOptions.setTrustStoreOptions

How to Reproduce?

Setup Spring Cloud Config Client with truststore and keystore and try to connect Spring Cloud Config Server with mTLS enabled. No client certs will be provided.
