This change allows users to skip TLS certificate verification on their
InfluxDB server, if they wish to do so, for instance when using self-
signed certificates.
Without this change, scrutiny failed to start and paniced with a
`x509: certificate signed by unknown authority` error.
When a transaction cannot lock the database, because it is already locked by another one,
SQLite by default throws an error: database is locked. This behavior is usually not appropriate when
concurrent access is needed, typically when multiple processes write to the same database.
PRAGMA busy_timeout lets you set a timeout or a handler for these events. When setting a timeout,
SQLite will try the transaction multiple times within this timeout.

retrying for 30000 milliseconds, 30seconds - this would be unreasonable for a distributed multi-tenant application,
but should be fine for local usage.
added mechanism for global settings (PRAGMA and DB level instructions).
fixes#341
Settings are loaded from the DB and added to the AppConfig during startup.
When updating settings, they are stored in AppConfig, and written do the database.
- updated dbdiagrams schema
- [BREAKING] force failure if `notify.filter_attributes` or `notify.level` is set
- added Settings table (and default values during migration)
- Added Save Settings and Get Settings functions.
- Added web API endpoints for getting and saving settings.
- Deprecated old Notify* constants. Created new MetricsStatus* and MetricsNotifyLevel constants.
devices with an empty wwn should be filtered out (not uploaded during device registration, skipped when attempting to upload metrics).
added a migration to delete existing device entries with an empty `wwn`
fixes#314
ensure DeviceStatus is a valid bit flag.
[docs] added running tests section to contribution guide.
make sure UI correctly treats scrutiny failures as failed.
