Download query results as csv file

[antonkovalenko]

Story

As an application developer I want to open query editor, run a query and be able to save query results as csv or compressed csv in order to process results in other application or send them to someone without an access to YDB UI.

Epic with steps

• design a way to save results of a query #2302
• long queries – support new operation type
• add new query type to a query settings form
• display query operations in query history
