Add bottle as dev requirement

[danimtb]

After running some test from a clean python environment I realized bottle was not installed.

Changelog: Fix: Included bottle package in the development requirements

The Changelog line should be: "Changelog: Fix: Included bottle package in the development requirements"

Tests in CI where working OK because bottle is installed in the requirements_server.txt so maybe this is not needed as our readme says:

Running the tests
Install python requirements

$ pip install -r conans/requirements.txt
$ pip install -r conans/requirements_server.txt
$ pip install -r conans/requirements_dev.txt
