Error when using commitWithin parameter

[pankajkgarg]

sunburnt throws an error, when commitWithin parameter is provided, while adding a new document.

For example

import sunburnt
si = sunburnt.SolrInterface("http://localhost:8983/solr/")
si.add({"id": 432, "text": "Hello World!"}, commitWithin=10000)

The error message thrown is

SolrError: ({'transfer-encoding': 'chunked', 'status': '400', 'content-type': 'application/xml; charset=UTF-8'}, '\n\n4000For input string: "10000.0"400\n\n')

This is happening because commitWithin parameter is converted to float before the request is sent.
