Incorrect naming and structure of roles in ansible_deployer

[Alexandre Levine]

Current ansible_deployer has roles like "install_contrail", "configure_contrail", etc..., which doesn't look like correct roles in term of names. They will be renamed and roles will be restructured a bit to fit new correct roles

Refactored roles in ansible_deployer.
Incorrectly named roles like install_contrail, configure_contrail, will be replaced with correct namings like "contrail", "kvm", "k8s", etc, and "contrail_deployer, "kvm_deployer", "k8s_deployer", etc. The difference is xxx roles are for deployment to nodes and xxx_deployer roles are to be run on the machine where ansible_deployer is run. Basically, these latter roles could've been named "contrail_ansible_deployer", "kvm_ansible_deployer", etc, because they fulfill roles of ansible_deployer for particular service.
