Removed embed_tools from MadHatter

[Pingdred]

Description

As discussed i try to move the embed_tools method from the MadHatter to ChechireCat.

Furthermore i added in CheshireCat the following methods that take care to interact with the MadHatter and the vector memory to embed tools :

• load_plugins
• install_plugin
• uninstall_plugin
• toggle_plugin

In addition the previous methods add a layer of abstraction to the components of the CheshireCat simplifying, in my opinion, the interaction with the plugin in the code and improve the readability.

@pieroit @nicola-corbellini let me know what do you think about this solution.
