Spring chore: add map params variants to update method

Comment From: hantsy

When I used Spring Jdbc in my latest projects, I found the update(String sql, SqlParameterSource paramSource, KeyHolder generatedKeyHolder, String[] keyColumnNames) lacks a variant to accept a Map instead of the SqlParameterSource.

This pr just add two variants to accept Map as parameter sources when binding params to sql.

• update(String sql, Map params, KeyHolder generatedKeyHolder, String[] keyColumnNames)
• update(String sql, Map params, KeyHolder generatedKeyHolder)

Thanks for the PR @hantsy but when more arguments are required, we fallback on SqlParameterSource. You can easily get one from the map by calling new MapSqlParameterSource(paramMap). Given how easy those methods can be called, I don't think the extra signatures are warranted.
