Filter internal Sidekiq data, and fix bugs

Changed

• Exclude more Sidekiq internal job attributes (cattr, tags, retry_for and unique_for) from the tags reported for Sidekiq jobs.

Fixed

• Continue reporting non-disk host metrics when a mount is frozen.
• Prevent a NoMethodError in the Active Job, Rake, Sidekiq, Delayed Job, and WebMachine instrumentations when the creation of an AppSignal transaction is interrupted by process shutdown signals.
