Ability to add calculated columns using Rest API

[parvinder_chana]

It will be nice to have the ability to add calculate columns using Rest API, similar to Measures. Currently I use lot of DAX expression to calculated columns, since you cannot add calculated column with Rest API, now I have to do all the calculation at my source (like in SQL server etc) and then use precalculated columns in Rest API.

After an entire project with Power BI, push datasets and Azure Functions this is a MUST!
