The new Roles_Pallet is now operational. next step before adding any other pallet:

• Update the chain_spec file with all the different genesis (use main_branch as model)
• Write the new tests
• Write proper pallet benchmarking
• Update the documentation

Concerning the new fixes & functionalities:

• No restriction on the number of roles one can have
• Servicer, Seller, & Notary roles requests need to go through a council vote for approval
• Corrected clippy warnings
• Sudo remains but is not used for roles attribution anymore. maybe we can use it to define the prime member in the Council pallet.

Additional remarks

• Due to the polkadot library upgrade, several functions in the original pallet required syntaxical corrections, this will also be the case for other pallets, without doubt.
• Replaced DispatchResults by DispatchResultsWithPostInfo whenever possible, as it is also extensively used in the substrate frame pallets.
