Enable formatting result set values

[igorlukanin]

Is your feature request related to a problem? Please describe.
This is a meta-issue with a list of issues related to formatting result set values:

• Support percents that are not multiplied by 100. #4565
• Rounding feature for SUM additive measure #9065
• Can we remove timestamp from time type dimension and return value format as yyyy-mm-dd using MSSQL database. #9076

Describe the solution you'd like
Looks like there are multiple cases when formatting the result set values after they have been retrieved would be useful.

Describe alternatives you've considered
Generally, SQL can be used to format (e.g., ROUND) values.
