simple recovery function added

[tschuyebuhl]

Summary

I added a simple recovery function and named return parameters to the ExecuteCommand function. Please let me know if this is correct. Would be grateful for any feedback. I'm new to the Mattermost ecosystem, we just recently joined the train in my org.

Ticket Link

This fixes #373.

Nice work, one suggestion below.

Thanks for the comments. I really appreciate it. Addressed both of them, hope that this is a step in the right direction and that the type assertion is not a problem.

LGTM, just one remaining suggestion to explicitly name the *model.AppError as appErr instead of err

One non-blocking suggestion to make the stack trace more readable:
