Chore: Upgrade to MeshKit v0.8.0

[leecalcote]

Current Behavior

go: github.com/layer5io/meshery-consul imports
	github.com/layer5io/meshery-adapter-library/adapter imports
	github.com/layer5io/meshkit/models/meshmodel/core/v1alpha1: module github.com/layer5io/meshkit@latest found (v0.8.0), but does not contain package github.com/layer5io/meshkit/models/meshmodel/core/v1alpha1

Desired Behavior
Use https://github.com/meshery/meshkit/tree/master/models/meshmodel/core/v1beta1, not v1alpha1.
