Test democracy on Rococo

[haerdib]

Include the token voting system pallet from #108 and perform the following steps:

Preparation

• Runtime upgrade of Rococo to include democracy & collective pallet
• Add a council via sudo call (Council.set_members(....))
• Add a technical committee via sudo call (TechnicalCommittee.set_members(....))

Remove sudo

• Remove sudo with a runtime upgrade proposal, external or public (see below)

Public proposal

• Propose two public proposals that need sudo privileges to be executed but do not matter much. For example, setting the balance of an account.
• Second one of them, such that it will be accepted as the next public proposal
• Once it's a referendum, try voting. Try to let it be accepted, to see it taking effect.
• Decline the second one.

(!) External proposal Runtime upgrade (v19 -> v20)

• Propose an external proposal via the council. Ideally, the next incoming runtime upgrade.
• Fast track the external proposal via the technical committee
• Try accepting the proposal once it's an active referendum and see it taking effect.

Update the council members via democracy

• Update the council members via proposal
• Optional: If it's an external proposal, try the different voting mechanisms compared to above (Simple Majority, Super-Majority Approve, Super-Majority Decline)

Update the technical committee via democracy

• Update the council members via proposal
• Optional: If it's an external proposal, try the different voting mechanisms compared to above (Simple Majority, Super-Majority Approve, Super-Majority Decline)

Treasury

• Try doing something with the treasury via the council.

Ensure the following

• A non-council member can not propose an external proposal
• A non-council member can not approve a treasury proposal
• A non-tech member can not fast track

I believe this can be closed now, as we already have democracy on Kusama.
