Problem with encodeURI with forward-slash in path param

[shashanka-wings]

I have a url

/api/namespace/{namespace}?query={query}

namespace path param value is AWS/EC2 (please note forward slash '/' in path param)

Now the issue is:

1. fetch-plus uses encodeURI (see this line in fetch-plus)

path = normalizeFunc(path.map(compute).map(encodeURI).join("/"));

So this escapes forward-slash, and hence the resulting url from fetch-plus is invalid

/api/namespace/AWS/EC2?query=1

2. If I use encodeURIComponent for the path param myself before passing to fetch-plus,
   encodeURIComponent('AWS/EC2') = AWS%2FEC2

valid path before fetch-plus:
/api/namespace/AWS%2FEC2?query=1

path converted in fetch-plus:
/api/namespace/AWS%252F?query=1

Notice that %2F is converted to %252F which is wrong. This is because of encodeURI.

So we cannot use fetch-plus in this scenario.

Please take a look.
