* Remove having to specify default error code. It is made implicit
instead. This removes some of the code clutter.
* Support returning multiple errors in a single API response.
Although this will be rarely used, introducing the provision in API
right now is better than later.
* Allow callers to pass both string and error types.
* Introduce a error code map which maps error codes (integers) to their
brief textual description.

Added extra argument to SendHTTPError function and added default error
code in all places.
To add a new error code, add entry in `pkg/api/errors.go` and then use
while calling SendHTTPError
