Add new float support to console autocomplete

Elasticsearch added a couple new data types, half_float and
scaled_float, so we should include those in Console's autocomplete
suggestions for mappings. Scaled_float also has a required parameter
called scaling_factor, which we suggest a sensible default for when
autocompleted. We talked about leaving the value empty, forcing the user
to pick a value, but the autocompleter doesn't seem to support blank
values.
