Remove EUI Dependency

[iporollo]

Description

We were originally using the EUI user interface library to build some of our components. We have since switched to the React Bootstrap library, but have not fully removed the EUI dependency (since we are still using some of their components for forms). The EUI dependency has unnecessary second order dependencies such as moment.js that we don't use but make the build heavier

Expected behavior

We need to refactor the forms that use EUI components into Bootstrap forms to fully remove the EUI dependency. Then, we need to delete EUI from the package.json.

Steps to reproduce

1. Go to Sources or Integrations page
2. Click on Create Data Source or Create Integration
3. Notice that the drawer is an EUI component

@iporollo Hi, I am a beginner. should the drawer look the same after it is replaced with react-bootstrap components?

[iporollo]

Hi @yokaiemporer! Appreciate you helping out here. Yes, ideally the drawer looks similar to the original one, with the color scheme being the boostrap primary color (purple) rather than the EUI blue.

Here's a link to the react-bootstrap components we're looking to replace it with: https://react-bootstrap.github.io/forms/overview/

And here's an example in the code where we already use those components for a form: https://github.com/monosidev/monosi/blob/master/src/ui/src/pages/app/onboarding/GettingStarted/index.tsx
