adding support for a collecto config file.

/scrutiny/config/collector.yaml

Adding ability to specify host identifier (label), that is updated on every collector run.
Can be specified by `host-id` CLI or `COLLECTOR_HOST_ID` env var.

Created a config class, interface and associated tests.

Created a "TransformDetectedDrives" function, that will allow users to insert drives not detected by Smarctl --scan, ignore drives that they dont want, and override smartctl device type.

Added Upsert functionality when registering devices.

Replaced "github.com/jinzhu/gorm" with "gorm.io/gorm" (ORM location moved, was using incorrect lib url)
Removed machineid library.
