Create Jenkins CI for auto builds for different versions

[PhilBarrett]

At the moment we have next Projects: Showcase , Helm , Scotland , React Admin , QEWD , QEWD-Courier. And our task is to make that those versions have to work when combined (eg. Helm + QEWD , Helm + QEWD-Courier etc.).

To avoid making mistakes by building them manually, we came up with a suggestion to make it with CI. For this was chosen Jenkins as OS.

Also, we came up that we would use one domain with sub-domains for versions, not IPs. And also we thought of doing this in the following steps:

• [x] 1. Update the server where we'd set up the Jenkins;

• [x] 2. To set up the docker for Jenkins;

• [x] 3. Install Jenkins in the docker and set it up;

• [ ] 4. Then we create Dockerfile for the build in docker;

• [ ] 4.1. Then we pull out Dockerfile from docker;

• [ ] 4.2. And send it to the server, where we can test it.
