### Description of PR
URL connectivity check in YARN Logs CLI can not connect to the RM on a
secured environment when getting the logs for a running application.
Jersey 2 upgrade introduced a new logic for checking URL connectivity before
getting the logs from the appropriate services.
This logic uses HttpURLConnection that can not load SSL configuration from
the ssl-client.xml on a secure environment. As I can see in such cases we need
to use HttpsURLConnection
### How was this patch tested?
Tested on a secured and unsecured environment:
- logs for a running application can be fetched on both
- when I stopped the NMs, retry logic keeps trying the connections
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`,
`NOTICE-binary` files?
