Change single Vault pki mount to multi pki mounts paths for etcd and kube CA`s (#1552)

* Added update CA trust step for etcd and kube/secrets roles

* Added load_balancer_domain_name to certificate alt names if defined. Reset CA's in RedHat os.

* Rename kube-cluster-ca.crt to vault-ca.crt, we need separated CA`s for vault, etcd and kube.

* Vault role refactoring, remove optional cert vault auth because not not used and worked. Create separate CA`s fro vault and etcd.

* Fixed different certificates set for vault cert_managment

* Update doc/vault.md

* Fixed condition create vault CA, wrong group

* Fixed missing etcd_cert_path mount for rkt deployment type. Distribute vault roles for all vault hosts

* Removed wrong when condition in create etcd role vault tasks.
