[explore] proper filtering of NULLs and '' (#4651)

* [WiP] [explore] proper filtering of NULLs and ''

TODO: handling of Druid equivalents

* Unit tests

* Some refactoring

* [druid] fix 'Unorderable types' when col has nuls

Error "unorderable types: str() < int()" occurs when grouping by a
numerical Druid colummn that contains null values.

* druid/pydruid returns strings in the datafram with NAs for nulls
* Superset has custom logic around get_fillna_for_col that fills in the
NULLs based on declared column type (FLOAT here), so now we have a mixed
bag of type in the series
* pandas chokes on pivot_table or groupby operations as it cannot sorts
mixed types

The approach here is to stringify and fillna('<NULL>') to get a
consistent series.

* typo

* Fix druid_func tests

* Addressing more comments

* last touches
