previously used app.jf.CacheExpiry = time.Now(), now either call
app.InvalidateJellyfinCache() (when we only need it to get a user),
or app.InvalidateUserCaches() (when the web user list needs to be
updated).
Webhooks send a POST to an admin-supplied URL when something happens,
with relevant information sent in JSON. One has been added for creating
users in Settings > Webhooks > User Created.
Lazily, the portion of GetUsers which generates a respUser has been
factored out, and is called to send the JSON payload.
A stripped-down common.Req method has been added, which is used by the
barebones WebhookSender struct.
jellyseerr already did this, but it's been standardised a little more.
Mediabrowser uses it's own genericErr function and error types due to
being a separate package, while jellyseerr and ombi now share errors
defined in common/.
in Settings > Discord, shown when a role is selected in "Apply Role".
The discord housekeeping daemon should pick up users deleted outide of
jfa-go too, so users who delete their own accounts should have their
roles removed (periodically).
shared "newUser" method is now "NewUserPostVerification", and is shared
between all routes which create a jellyfin account. The new
"NewUserFromInvite", "NewUserFromAdmin" and "NewUserFromConfirmationKey"
are smaller as a result. Discord, Telegram, and Matrix now implement the
"ContactMethodLinker" and "ContactMethodUser" interfaces, meaning code
is shared a lot between them in the NewUser methods, and the specifics
are now in their own files. Ombi/Jellyseerr similarly implement a
simpler interface "ThirdPartyService", which simply has ImportUser and
AddContactMethod routes. Note these new interface methods are only used
for user creation as of yet, but could likely be used in other places.
