Add support for other column types

[lsmacedo]

Some data parsing might be necessary to insert into tables that are not of type text (not yet tested).
Ideally, RDM should be able to run a database introspection to determine the correct column types.
Focus on getting text, boolean, integer, float and date working for this issue.

SELECT
    column_name,
    data_type
FROM
    information_schema.columns
WHERE
    table_name = 'table_name';
