Add a new pattern to allow moving the flag handling out of the collector
package and into a separate package. This allows collector package users
to create their own config or flag handling.

The new `lnstat` collector produces a high number of metrics, per-cpu,
and results in approximately double the number of metrics previously
scraped. For example, a typical server with 64 cores produces 3832
lnstat metrics compared to 4147 metrics for the remaining collectors.
Therefore disable the `lnstat` collector by default.
