Add dependency verification mode

This commit introduces a selection of the dependency verification

mode. There are 3 different modes: strict (default), lenient and

off.

The lenient mode has been added because dogfooding the feature showed

it could be painful to udpate the dependency verification

metadata file without such an option: often we want to diagnose

why a dependency is here, but as soon as the dependency

verification file is present, verification is active and immediately

fails the build.

This effectively prevents from using the usual tooling to check

where a dependency comes from. The workaround was to temporarily

rename the file, run the build, then rename again, which was tedious.

So, instead of adding a mode where verification would be totally

ignored, this commit introduces a mode where the errors are turned

into warnings. This doesn't totally silence the problems, which

makes them more visible to the developer.

The "off" mode is for use cases where users prefer not to deal

with upgrades locally, but want to see verification happening

on CI only.
