> Use proper capacity for base 10 storage units

> Key: IMPALA-11804
> URL: https://issues.apache.org/jira/browse/IMPALA-11804
> Project: IMPALA
> Issue Type: Task
> Components: Backend
> Reporter: Abhishek Rawat
> Assignee: Jason Fehr
> Priority: Major
>
> Most cloud vendors advertise storage in base 10 units such as KB, MB, GB, TB.
> Impala considers these storage units to be base 2. This could cause issue
> because when configuring data_cache or scratch_space Impala could try to use
> more capacity than what the underlying storage provides.
> It's okay for Impala to use base 2 units, but it should support configs using
> base 10 units and also use proper units (KiB, MiB, GiB, TiB) internally and
> everywhere else such as web UI, query profile, etc.
> The logic for parsing memory configs is here:
