Implement IUrlParameter on Time (#3222)

* Implement IUrlParameter on Time

This commit implements IUrlParameter on Time so that the conversion to a
string value happens when building the url.

Add condition to ElasticsearchUrlFormatter to convert TimeSpan to Time unit
string value when building the url.

Remove special case handling for Time and TimeSpan and re-run API generation

Fixes #3220

* Remove superfluous code
