Web UI tests: Get rid of *_cert_path and *_csr_path config variables
Web UI tests now don't require additional configuration to test certificates.
Self-signed certificates and CSR are generated on fly.
Next variables from ~/.ipa/ui_test.conf for now are deprecated:
- arbitrary_cert_path
- service_csr_path
- user_csr_path
