[vtk-developers] [buildbot] Retiring the dashlin1 builder

[Ben Boeckel]

Hi,

With the recent merge of VTK-m into VTK, it has exposed a problem with
dashlin1: it's Git is too old to support the commands we use to ensure
the source directory is set up properly. With the deprecation of OpenGL1
as well, I propose that we retire the builder. OpenGL1 is still tested
by bigmac at least and eeloo covers the other feature flags already.

Thoughts?
