* feat: expose metrics path & init analyzer errors metrics This commit add metrics path & the analyzer error metrics in the codebase. The changes have been made across all analyzers and include the addition of a new metric with label values for the analyzer's name, analyzed object's name, and namespace. The metric's value is set to the length of the analyzer objects failures.
