Prefix deployment ID with the cloud provider identification

[amarthadan]

Prefixing deployment ID with the cloud provider identification will allow us to access only the cloud provider hosting the deployment for info and other commands.
More information in the Slack discussion

Part of this is also a refactor of the info command mentioned in #1477

Hi, I've tested this in conjunction with the deployment ID-based removal. The IDs are all prefixed depending on the cloud I'm uploading to; I did not notice any mishaps (i.e. no incorrect prefixation).
