speed up image builds

[e-carlin]

Compiling epics take a while. That code is unlikely to change so it doesn't make sense to wait for it at each build.

Some ideas:

• Create an epics base image and then layer slicops on top
• Create an epics rpm and install it.

[robnagler]

I noticed a couple of things:

• Remove motif or libXt. This will make the image smaller, maybe by a lot, because this brings in all of X11.
• The base epics build can be parallelized. It may be the ASYN build cannot so you can build that later, I think.
• We may not need to build ASYN separately. It was needed for the medm modules, which are no longer needed. We might want to use the one with SYNAPPS, this definitely can be parallel.

[robnagler]

Could maybe remove the testApp/Ca parts as well. There are other tests such as ntndarrayTest. The linking is a slow part.

[robnagler]

We already have an epics rpm. We could add SYNAPPS to it.

Tried to use rscode-epics and rscode-epics-asyn, but got this strange error building synapps:
