Linting: show a soft warning if variables are overridden with default value

[fahad19]

Currently

• We have linting for checking entity shapes: https://featurevisor.com/docs/linting/
• Features can have variables schema with their default values defined: https://featurevisor.com/docs/features/#variables
• Those variables can be overridden too: https://featurevisor.com/docs/features/#overriding-variables

Variables always fall back to their default value, and do not need overriding if that's the value you desire for e.g. at rule level.

Proposal

Throw a soft warning (without exiting with an error code) when running $ featurevisor lint if variables are overridden with their same default value, because it is redundant.

Where?
