Cannot export dashboards if password contains a "/"

[jake-low]

Wizzy version: 0.5.9

I discovered this when attempting to export local dashboards to a Grafana instance using the username admin and a password containing a /, which for explanatory purposes let's pretend was pass/word. Setting the password to pass/word using wizzy set grafana and then trying to run wizzy export dashboards resulted in the following error:

# wizzy export dashboards
/app/node_modules/sync-request/index.js:37
    throw new Error(response.error.message || response.error || response);
    ^

I suspected that this might be because the password is being used to construct a URL of the form https://user:password@hostname, and the password wasn't being URL-encoded. So I changed the password in Wizzy's config (but making no change in Grafana) from pass/word to pass%2Fword. This fixed the problem... for wizzy export dashboards. But it broke other commands, such as wizzy list dashboards, which worked before but now result in a 401 error:

# wizzy list dashboards
Grafana API response status code = 401
No error body from Grafana API.

I think this bug would be fixed by URL-encoding the password when constructing a URL that gets used in an API call somewhere beneath wizzy export dashboards. The desired behavior of course is for pass/word to work correctly for all commands, without the user having to think about percent-encoding weird characters.

Let me know if you need further details to reproduce this. And thanks for maintaining Wizzy! It's a really useful tool.
