### Description of PR
The WebUI file explorer (/explorer.html) is the main entry point of HDFS for
many users in our environment. Most of them access HDFS through browser
behind Knox gateway, not by hdfs CLI. But current file explorer is missing
some basic features that users expect from a file manager today.
We have run patched version of file explorer on our internal 3.1.2 fork for
more than 2 year. It serves daily user traffic without big issue. We want to
contribute the general part to upstream as one patch.
Adds the following to `/explorer.html`:
- Open at user's home directory (from WebHDFS `GETHOMEDIRECTORY`) instead
of `/`.
- Keep current path across login redirect via new `?p=<urlencoded-path>`
query.
- Show current nameservice name next to the directory input.
- Upload progress bar with percent and elapsed time (per file for
multi-file upload).
- Success message in info panel after mkdir / upload.
- Trash support: delete now moves the target to
`<homedir>/.Trash/Current/<path>` using
`op=RENAME&renameoptions=TO_TRASH`
instead of `op=DELETE&recursive=true`. Two guards reject moving a path
that is already inside Trash, or that contains Trash root. Destination
name collision is handled by `.1`, `.2` suffix.
- Direct delete button is removed in this patch.
- Rename file/directory via `op=RENAME`.
- Show access time next to modification time.
- Submit create-dir and rename input on Enter key.
- "Copy" button to copy fully-qualified `hdfs://<ns><path>` to clipboard.
