Add gnome keyring

[saw-jan]

Added gnome-keyring keyring provider.

Test logs with:

• image WITHOUT gnome-keyring

  [ warning sync.credentials.http.legacy ]:   Migrating old keychain entries failed "The name org.freedesktop.secrets was not provided by any .service files"

  • image WITH gnome-keyring

    [ warning sync.credentials.http.legacy ]:   Migrating old keychain entries failed "Entry not found"
