🌱 KCP: make EtcdMemberHealthy less verbose on client creation failures

[chrischdi]

What this PR does / why we need it:

The error in the condition looked like:

Failed to connect to the etcd Pod on the test-fq2s6-xrmcd Node: could not establish a connection to any etcd node: unable to create etcd client: failed to get etcd status: context deadline exceeded

After that only the most detailed error gets shown (via unwrapping):

Failed to connect to the etcd Pod on the test-fq2s6-xrmcd Node: context deadline exceeded
