Is your feature request related to a problem? Please describe.
Currently when bumping dependencies it is up to the developer to ensure all .txt requirement files are updated as needed and this can be error prune.

Describe the solution you'd like
An automated make pip-compile make command that:

• sets the dependencies between different .in files
• provides command to run to compile affected .txt files (via the dependencies)
• also set up a CI step that runs pip-compile when changes in requirements folder is detected

Describe alternatives you've considered
Currently way is the alternative: human checking and it is error prune.
