Clone Space Data or Create Alias for Space

[wbqtac]

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

If original space name is not desired, we need have the function to create alias or completely clone that space.

Describe the solution you'd like

create space alias <alias_space_name> as <old_space_name>

Describe alternatives you've considered

Make a full copy of the space. Current operation "create space as" only copy the schema

Additional context

Is there any solution already available? I checked br backup and restore, but it looks that restore can only restore to original space name snapshot looks has similar function.
