Add support for more datatypes to Query Builder filters

[vadimp]

Currently, QB filters support only simple data types (strings, numbers, etc...) with relevant comparison operators.
Having support for Map, Array and may be a few more will enrich the possibility of QB.

For example, a simple filter by map value with known key is is not possible (ResourceAttributes is a map).

AND ( ResourceAttributes['k8s.namespace.name'] = 'my-namespace' )

In the below screenshot, ResourceAttributes field is treated as a standard data type.

Specifically for maps, I don't expect any key listing functionality. The key should be provided by the user explicitly.

Arrays filtering should follow the same idea. The ability to specify:

• Array entry
• Array range
• Whole array

With the relevant comparison operators including:

• Equals (full array equality)
• Contains
• Starts with
• Element at position equals to value
• ...

As of v4.x you can write in column names and filter values. We even have special support for the map type where a field is populated with map suggestions:
