Subject: [PATCH] cli: gracefully handle errors during state data retrieval

In the event of a failure to fetch state data, merely print the error
received from holod instead of abruptly terminating the CLI.

Example:
```
holo# show state /invalid/path
% failed to fetch state data: status: InvalidArgument, message: "Failed to get operational data: invalid YANG data path" [snip]
holo#
```
