This patch simplifies the user and organization registration and query
for the UI. The pattern clients are expected to follow is to create if
the get fails. For example, the following pseudo-go-code is the
expected calling convention:
var entity *ent.User
entity, err := Get()
if err != nil {
if ent.MaskNotFound(err) == nil {
entity = Create()
} else {
return err
}
}
return entity
This patch adds the following service methods. For initial
registration, all input data comes from the id token claims of the
authenticated user.
```
❯ grpcurl -H "x-oidc-id-token: $(holos token)" jeff.app.dev.k2.holos.run:443 list | xargs -n1 grpcurl -H "x-oidc-id-token: $(holos token)" jeff.app.dev.k2.holos.run:443 list
holos.v1alpha1.OrganizationService.CreateCallerOrganization
holos.v1alpha1.OrganizationService.GetCallerOrganizations
holos.v1alpha1.UserService.CreateCallerUser
holos.v1alpha1.UserService.GetCallerClaims
holos.v1alpha1.UserService.GetCallerUser
```
Remove the server.Config struct, not needed. Remove the app struct and
move the configuration to the main holos.Config.ServerConfig.
Add flags specific to server configuration.
With this patch logging is simplified. Subcommands have a handle on the
top level holos.Config and can get a fully configured logger from
cfg.Logger() after flag parsing happens.
Disambiguate the term `core` which should mean the core domain. The app
is a supporting domain concerned with logging and configuration
initialization early in the life cycle.
