Add PAMR+SSH support for cloud-provided VMs

[paraita]

Support cloud instances for PAMR over SSH

• Fixes the problem where the remote instance is not aware of its public hostname or ip and can't resolve it to its networks interfaces (which is the case in cloud-provided instances or when there's a load-balancer involved)
• Refactor some code to improve readability
• Clarify the sshHost and remoteHost variables
• Applied the coding-rules formatting
• Clean code for readability
• Ignore the intellij out folder
