Lr/vote collector

[lukaszrzasik]

Closes #3564

This PR:

• Adds a dishonest_voting test that shows the original issue.
• Adds a wrapper NetworkEventTaskStateModifier which can change NetworkEventTaskState's behaviour for testing purposes.
• Old consensus, new consensus, DA and Upgrade tasks now store a BTreeMap of vote collector tasks. When a vote with a higher view number arrives, it doesn't overwrite the existing vote collector for a different view. Those collectors can accumulate votes for different views in parallel. When the threshold is reached the collector is removed and all the collector for the older views are removed as well.
• Creates a helper function handle_vote to avoid code duplication

This PR does not:

Does not change vote collecting for ViewSync tasks as these differ in the vote collecting logic. As far as I understand they are not susceptible to the original issue as well.

Key places to review:

Changes in the crates/task-impls/src/vote_collection.rs file. Especially the garbage collecting logic. I'm not sure about it.
crates/task-impls/src/network.rs file for the new testing wrapper.

How to test this PR:

All CI tests should pass, including the new test.
