Remote multi-server automation tool
b56206e9ce
This syntax allows servers to be specified long-hand including properties.
The `role(:my_role, %w{example.com, example.org})` is convenient for batch
set-up of servers; but as SSHKit provides arbirtary properties on servers, it
might be handy to set up servers in long hand:
server('example.com', roles: :my_role, my_property: "my_value")
server('example.com', roles: [:my_role, :another], my_property: "my_value")
server('example.com', roles: :my_role, primary: true)
This commit adds the ability to do this.
