* This commit adds a --disregard-incompatible-hpas that makes the HPA
provider stop erroring out when a collector cannot be created for a
metric in a HPA. Useful when kube-metrics-adapter runs alongside another
metrics provider. Fixes issue #94.

* Wraps the Plugin Not Found error in a new type that can be checked by the caller of a function to determine if its contents should be logged or added as an event to the HPA, when this HPA is incompatible.
The disregardIncompatibleHPAs is now targetting only the log or addition of the same event.

* Invert if expression to select when we should log
CreateNewMetricsCollector errors: don't log when both conditions are true - it's not a PluginNotFoundError
and disregardIncompatibleHPAs flag is set to true. This way, if an error
is NOT PluginNotFoundError it will always be logged, and when it IS
PluginNotFoundError it will only be logged when
disregardIncompatibleHPAs is false.
