> Close child file systems in ViewFileSystem when cache is disabled.

> Issue Type: Bug
> Reporter: Shuyan Zhang

> When the cache is configured to disabled (namely,
> `fs.viewfs.enable.inner.cache=false` and `fs.*.impl.disable.cache=true`),
> even if `FileSystem.close()` is called, the client cannot truly close the
> child file systems in a ViewFileSystem. This caused our long-running clients
> to constantly produce resource leaks.
