Introduce 'entrypoint.sh' for some Containers

[ashahba]

Description

This PR introduces an entrypoint.sh script to be run at Container startup which is a very common practice by Container developers.

Issues

There are times where more than a single command is required to be run at container entry point and having a script would simplify the Dockerfile design greatly.

Type of change

List the type of change like below. Please delete options that are not relevant.

• [N/A] Bug fix (non-breaking change which fixes an issue)
• New feature - Pack multiple commands into an script and run that script at Container startup rather than a single command within the body of the container
• [N/A] Breaking change (fix or feature that would break existing design and interface)

Dependencies

None.

Tests

• Container builds are successful
• Running the entrypoint.sh script is relatively fast and does not introduce unacceptable wait time for prompt to be ready
• Running containers produces output similar to the following which is the expected result:
