The first implementation of unifyfs-shell utility.

[sandrain]

Currently, this is not going to be too useful because ls command is not available. We can add more useful features as the client API becomes available.

Description

An implementation of the unifyfs-shell utility program, which allows interactive shell-like interface to explore the unifyfs file system.

I've opened an issue for an alternate proposal that would use busybox as our UnifyFS shell here: https://github.com/LLNL/UnifyFS/issues/426. Please post any comments about it in that issue, as I don't want to spam this pull request with busybox-related comments.

Marking this WIP until we decide if the busybox option (issue #426) is viable

We decided to move in a different direction with this, since LD_PRELOAD and busybox works to some degree.
