Admin: add `src admin create` command
Created by: jdpleiness
Add src admin create
command to setup an initial admin account on a new deployment of Sourcegraph. This is mainly useful for CI pipelines and integration testing purposes in which a Sourcegraph deployment will be deployed in an automated way.
This functionality was previously tied to the experimental src validate
command but was removed.
Test plan
Locally tested changes using latest Sourcegraph Helm install.
ran go test ./... - all tests passing ran staticcheck ./... - no issues found in new code
