♻️ Maintenance/new settings (2nd round)

[pcrespov]

What do these changes do?

This is the second of a series of PR that will progressively introduce the new-settings (i.e. move from trafaret to settings_library ) in the entire repo.

In previous PR #2736 we mainly extended the settings-library with new settings classes and utils.

Instead, this PR will focus on replacing trafaret from the web-server. There are over 20 plugins affected by the configuration so the goal of the PR is only to isolate dependencies without breaking the app.

The trafaret-based configuration of the webserver is based on the composition of schemas for each plugin, typically individually defined in *_config.py, into a single application schema in application_config. In order to isolate the dependences, we will split each configuration module into two: *_schema and *settings, such that

• *_schema: keeps trafaret's schema only. This way trafaret import is isolated here.
• *config.py: keeps constants and helper functions to access config section stored in app.
• *settings: placeholder for future service-settings library based settings (some already contain some pydantic settings).

Therefore, after this refactoring every plugin will look either

• folder-like plugin

plugin/
     _schema.py
     config.py
     ...
     module_setup.py
     settings.py

• or analogously for flat plugin:

plugin__schema.py
plugin_config.py
...
plugin_settings.py
plugin.py

Next PR in the series will include the settings-library in the webserver and create settings for each of the library in the *settings.py module.

NOTE: @mrnicegyu11 , @Surfict : in the next rounds, the env vars to configure osparc-simcore might be affected so I will start adding you as reviewers.
