HTTP input is not properly encoded.

[artursouza]

Expected Behavior

If the value of a state store (for example) has a "/", then it does not affect the URL path and the Dapr API works as expected.

Actual Behavior

Dapr returns Method Not Allowed error because "/" (and other special chars) affect the URL path.

Steps to Reproduce the Problem

Try to save state where state store contains "/" in the middle of the name.

Release Note

RELEASE NOTE: FIXED input encoding for HTTP calls.

breaking change since constants are removed in #428

[artursouza]

This is not breaking change because those constants are public simply because they are used in other packages internal to the SDK. In Java there is no way to mark that as internal like in .Net.
