Grep, replace do not work at the Vault root

[mattlqx]

The most broad you can use these commands today is that the top of a KV store. You can't use them at the "root" of a server to search all KV stores. It would be nice if an entire Vault can be searched rather than having to specify every KV store.

https://localhost:8200 /> grep foo ./
Not a valid path for operation: //
https://localhost:8200 />

Good point. Im refactoring to uniform the traversal functions for concurrency #86
I think with that I can also fix this issue.

Didn't have much time lately to work on this. But will try to get to it soon again :)
