Update doxygen version in docker image. (#840)

* Update doxygen version in docker image.

+ The docker image has a different version of doxygen than the ccs-net
  machines.  This occasionally results in different nightly regression and CI
  behavior for the autodoc target.
+ Update doxygen in the docker image to 1.8.14 to match ccs-net.

* missed a ref to the docker image. fixed.
