datafusion-cli crate has circular dependency

[andygrove]

Describe the bug

datafusion-cli currently depends on both ballista-0.6.0 and datafusion-7.0.0. ballista-0.6.0 depends on datafusion-6.0.0.

To Reproduce
N/A

Expected behavior
If we have one CLI that depends on both DataFusion and Ballista then it implies that we need to always release DataFusion and Ballista and release the CLI last.

Additional context
None
