Multi client support on one instance

Planned feature

One AWS instance should host multiple clients and multiple client implementations

AWS Instance naming: host-{hostnr}, from 00000 - 99999 -> up to 10000 hosts

Each host can host up to 1000 clients of the same implementation

client naming: client-{client_implementation}-{clientnr}

An individual client can then be addressed something like: host-05464-client-go-365.

Port mapping:

• 30000 + yyy -> p2p port of go client

• 31000 + yyy -> p2p port of cpp client

• 32000 + yyy -> p2p port of python client

• 20000 + yyy -> json-rpc port of go client

• 21000 + yyy -> json-rpc port of cpp client

• 22000 + yyy -> json-rpc port of python client

Steps:

• Ansible playbook addressing multiple clients per hosts
• setup a process manager to handle docker logs (ansible does support this only for single commands)
• change logic to generate node id
• refactor python controller semantic,now a host != a client
• refactor scenarios to use the new semantic.
