Description of problem:
The masthead (header area) of BPMS is not yet RCUE compliant. We need to update this with the specific color, font and spacing values provided in the RCUE project.

For the product version, see here: https://rcue-uxd.itos.redhat.com/brand-integration/
To access the RCUE css, you must request access from rhamilto, at which point you will be granted access to the github repo.

For the community version, please use the Patternfly styling for the masthead (which has a different color scheme), from the Patternfly github: https://github.com/patternfly/patternfly
