restructure baremetal configuration - backport 4.13

[dahorak]

This is backport of #9274

Move BM configuraiton from AUTH"[baremetal"] and AUTH["ipmi"] to ENV_DATA["baremetal"] and ENV_DATA["baremetal"]["servers"] respectively.

This is just cosmetic change, but I think it will make the code and config little bit more readable and clean. (Right now for example the AUTH["ipmi"] section contains also information about the network configuration of the server (IP, MAC,...) and disks, so I think it make more sense to name the section differently and also have all the configuration related to the particular baremetal environment in one section (ENV_DATA["baremetal"]).

The configuration now looks like this:

ENV_DATA:
  baremetal:
    bm_private_nic: "..."
    bm_httpd_server: "..."
    bm_httpd_server_vm: "..."
    bm_path_to_upload: "..."
    bm_install_files: "..."
    bm_httpd_server_user: "..."
    bm_tftp_base_dir: "..."
    bm_tftp_dir: "..."
    bm_dnsmasq_dir: "..."
    bm_status_check: "..."
    bm_provisioner: "..."
    bm_provisioner_user: "..."
    servers:
      host001.example.com:
        mgmt_console: '...'
        mgmt_username: '...'
        mgmt_password: '...'
        role: '...'
        cluster_name: '...'
        public_mac: '...'
        private_mac: '...'
        ip: '...'
        root_disk_id: '...'
      host002.example.com:
        mgmt_console: '...'
        mgmt_username: '...'
        mgmt_password: '...'
        role: '...'
        cluster_name: '...'
        public_mac: '...'
        private_mac: '...'
        ip: '...'
        root_disk_id: '...'
      ...
