[feat]: Creating grouping for counter table types in tree under keyspace

[millerjp]

Add a grouping to the list of tables under the parent keyspace in the tree where where counter tables are grouped into types.

eg Counter - this is where the table contains a column with a data type of counter

CREATE TABLE IF NOT EXISTS cycling.popular_count (
  id UUID PRIMARY KEY,
  popularity counter
);

Add a system setting to "Group Tables by type" to enable/disable this feature.
