As part of this task I will work on a setup of containers for EFDWriters + Database (MariaDB and Influx), then I can introduce kafka to the same environment.

I have created a dockerfile to deploy EFDWriters from the RPM:

https://project.lsst.org/ts/lsstrepo/ts_EFDruntime-3.9.0-690.el7.centos.x86_64.rpm

There are mutiple dependency issues: 

1. .The LD_LIBRARY_PATH is not pointing to the right directory
2. Missing mysql library for mariadb efd writers: (```./sacpp_ATDome_event_efdwriter: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory```)
3. Missing mysql library for kafka efd writers

Fixes:

1. Update in setupEFD.env  to use the right path: export LD_LIBRARY_PATH=${SAL_WORK_DIR}/lib:${LSST_SDK_INSTALL}/lib
2. add mariadb-devel to dependencies
3. add librdkafka to dependencies

created dockerfiles on github for efd_writers, they are in: https://github.com/lsst-ts/ts_Dockerfiles/tree/tickets/DM-19243

Also pushed efd_writers containers in: https://cloud.docker.com/u/lsstts/repository/docker/lsstts/efd_writers

I have updated the ts_EFD rpm on the project.lsst.org/ts/lsstrepo to require mariadb-devel and librdkafka,
and changed the LD_LIBRARY_PATH in setupEFD.env

reviewed all the list in the following youtube channel to learn about Kafka:

Also created docker images in lsstts/ for efd_writers and have docekr compose to create mariadb as well.

Andres did a bunch of research for the Kafka Influx implementation, but we have since switched directions and are using DM implementation.  This research still will apply for stuff we do later on the down the road.
