[metric]Rename column name with non-english string

[heartcored98]

Is your feature request related to a problem? Please describe.

Hi, I am really enjoying superset, but I am frustrated when I have to rename column with non-english string.
Because if I try to change the column name in Korean (for example metrics column), then generated sql query contains Korean with AS statement. Therefore, BigQuery engine is broken.

Describe the solution you'd like
I would like to manually assign column names of group by and metrics with any-language string, through the chart explore ui.

Since bigquery column name rule does not allows non-english character, I think a field name variable should be prepared separately from the column name in SQL query.

Describe alternatives you've considered

Are there any updates on the issue? This issue is very annoying when using Superset with BigQuery.
