Update Dockerfile for successful build

[MattKing06]

Changes Summary

• Removed apt-get cmake as it was the wrong version for bmad and higher versions were not available via apt-get, now building cmake.3.18.4 (suggested by bmad) from source
• Added pango1.0-dev to apt-get list for bmad dependency
• bmad installation did not create any files in /bmad/tao/python so just installed pytao using pip3 install
• included lcls_elements.csv in MANIFEST.in so setup.py brings it into the install location
• Added pyepics, scipy, and lcls-tools (from source via git) to python3 dependencies
• Added lcls-classic-lattice git repo to dependencies for model_service.py, could not find repo for lcls-lattice.
• Added pango1.0-dev dependency for secondary image (after sim_builder creation)

Closes #99

---

The following services did not run due to model_service.py not working properly (mentioned in comment below):

• bpm_service
• camera_service
• fel_service
• klystron_service
• magnet_service
• model_service
• obstruct_service
• undulator_service

The following services do not require the model for the PVs to go live, and so can be tested below:

• sc_rf_service
• sc_magnet_service
• decarad_service
• generic_pv_service

To Test

Docker build

• checkout 99_update_dockerfile_for_successful_build branch
• run docker build -t simulacrum . (takes quite a long time..)
• wait until build completes
• run bash ./start_container.bash
• after this you should see root@<container-id>:/# which means the container built successfully.

Service Test (sans-model)

• Once in the container, you should be able to go into ./simulacrum/sc_rf_service and run python3 ./sc_rf_service.py &
• On the host machine (outside of the container) you can try to caget/camonitor/caput-to the PVs created by the sc_rf_service (i.e. ACCL:L2B:1400:RACKA:HWINITSUM)

Current output from model_service (after lattice and dependency installation):

    plot=model_service_args.plot)

    raise RuntimeError('Thread has no running event loop')
RuntimeError: Thread has no running event loop

RuntimeError: Empty SharedPV

I can't see any other example of SharedPV use in this repo for comparison.
