Change Confirmations to Confidence

[EasterTheBunny]

Confidence is a different approach to mapping a chain agnostic concept of confidence that an event or transaction can or should be acted on. Confidence is intended to map to defined levels of confirmations on EVM chains and other states on other chains.

Only two levels of Confidence exist by default to define the boundaries: Highest and Lowest. This creates an inclusive range for all chain configurable Confidence levels and can be treated as % confidence that an event or transaction can or should be acted on.
