'Create your monitor' Docker container Inconsistencies

[jnovack]

Describe the bug
I'm sure I read/heard somewhere that this feature is broken in this version bluewaveuptime/uptime_server sha256:c5392a65a06b2df1760267e4e1beb34ad57bdd3bfa6e1a6f8300c3a6142deb29. However, I want to document the things found (if they are fixed already, please close).

1. When selecting "Docker container monitoring", the Container ID is always red.
2. Error message states "Please enter a valid URL". Validation should just be alphanumeric with optional dots, dashes and underscores.
3. Support Swarm. Monitor the service to make sure the actual replicas equals the requested replicas, not the specific container name (which changes).
