* Move tenant.Service unit tests into its package
* Delete the top-level TenantService interface now that it's not used.
* Move helper funcs for setting up test stores into testing pkg
* Delete duplicate implementations scattered through the codebase
* Move error assertions into store-creation helpers
This includes removal of a lot of kv.Service responsibilities. However,
it does not finish the re-wiring. It removes documents, telegrafs,
notification rules + endpoints, checks, orgs, users, buckets, passwords,
urms, labels and authorizations. There are some oustanding pieces that
are needed to get kv service compiling (dashboard service urm
dependency). Then all the call sites for kv service need updating and
the new implementations of telegraf and notification rules + endpoints
needed installing (along with any necessary migrations).
feat(dashboard): add owner ID to dashboard model
This adds the explicit OwnerID field to Dashboard and also adds a
migration which populates dashboard owners IDs based on dashboard owner
URMs.
feat(dashboards): isolate service in own package
This change isolates the dashboards service into its own package. It
also updates the API to no longer interface with user resource mappings.
Instead it defines new handlers which rely on the newly populated owner
ID field.
chore(dashboards): port tests from http package into new service transport package
chore(launcher): use dashboard transport package client in launcher tests
chore(kv): remove now defunkt dashboard service implementations
