Feature/arsn 177 introduce archive field in metadata

[williamlardier]

This new metadata field is introduced as part of the Cold Storage epic.

The suggested format is a class in the same way as #1855.

Here, we enforce a specific order of fields edition:

• The archiveInfo is required when creating the object
• Both restoreRequestedAt and restoreRequestedDays can be only set if archiveInfo is set (because the latter is mandatory when creating the object)
• Both restoreCompletedAt and restoreWillExpireAt can be only set if restoreRequestedAt and restoreRequestedDays are set, because the restoration completion comes after the restoration request.

Once the object is restored and the restoration expires, the archive field can be re-computed by keeping the archiveInfo field only.

The field setter will make sure the provided object is of the right type or is valid using the isValid static function of the new class.

Unit tests are added to make sure the class behave as expected.
