Sync vagrant environment with production instance of Anitya

[Zlopez]

The current vagrant environment is pretty outdated and doesn't use the same packages as production. We need to sync these to prevent deployment issues.

Here is the list what needs to be done:

• Use fedora provided packages where available
• Freeze versions of packages to versions provided by fedora (Use >=)
• Remove packages that are no longer needed
• Update vagrant to Fedora 32

Let's use poetry for dependency management.

I decided to not use poetry in the end, because this will need different approach to installing and handling dependencies at all. Instead I decided to go with requirements.txt and usage of >= and < to prevent any breaking change. I hope this will be enough.
