-Adds heading with new layout consistency class name
-Adds open in new window functionality

Resolves: openbmc/phosphor-webui#81

Tested on a Witherspoon with power on and with build
that allows up to 4 kvm sessions connected
at a time https://gerrit.openbmc-project.xyz/c/openbmc/bmcweb/+/25231.

KVM console loads in firefox, chrome, safari, edge and IE11.
Opening new window and returning to parent window is
functional across all browsers.
