[Doc]: Add a developer guide section in the documentation

[LorenzoTettamanti]

Is your feature request related to a problem?

• Yes

  Problem Description:

  Up to now the entry level for the development process has a very steep curve. Resources are sparse in the internet and the existing webpages such as epbf.io and aya-rs.dev only covers the top of the iceberg. Although the first thing to do to ensure that newbies can learn and become maintainer of the project is a detailed developer guide.

  Solution:

  Describe the solution you'd like

  • A new section in the documentation with the Developer Guide where we can place the Agent API Overview, development goals, Github discussions references,etc..
  • Update the Documentation with the latest integrated metrics

  Additional info

  • Documentation uses mkdocs and mkdocs-material python libraries
