v1.1.1 Expand configurability

Make the following sshd options configurable via env vars:

• ClientAliveCountMax via CLIENT_ALIVE_COUNT_MAX
• ClientAliveInterval via CLIENT_ALIVE_INTERVAL
• TCPKeepAlive via TCP_KEEP_ALIVE

v1.1.0 Add user:ssh provisioning

Enables provisioning of SSH keys per user a-la GCP, i.e. user:public_key

Example of the provisioning config:

cloudysanfrancisco:ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDAu5kKQCPF...
baklavainthebalkans:ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABgQDQDx3FNVC8...

v1.1.0-beta8 Replace last approach with simply disabling the user password in /etc/shadow

Using a star * instead of a bang !, keeps the user account unlocked, but still disables login by password by keeping the password invalid.

Effectively this leaves only the option of public key ssh login.
