Add mainnet solver rewards dashboard and update with service fee

[harisang]

This PR adds the following to the repo:

• Query 2510345, which is the main query showing in the solver rewards dashboard.
• Query 4017925, which computes whether a solver needs to pay the CoW DAO bonding pool service fee or not.

Note that query 2510345 has some proposed changes, regarding the implementation of the service fee and the reduction in the rewards being transferred to solvers. The changes are between lines 746-811.

So the plan is to get the PR approved, and before merging actually edit query 2510345 to ensure its code is identical to the code in this PR.

[fhenneke]

This is a good opportunity to clean up this query (and the respective solver-rewards query).

As a minimum, the external queries referenced in this query should be called instead of their code being copied.

There is much room for other improvements, but some of that (e.g. using the actual solver-rewards query for the dashboard or using query 4021306 from coincidence of want for slippage) could be addressed later.

[fhenneke]

That whole block should be replaced with something like

named_result as (
    select * from query_2283344(bonding_pool_data='{{bonding_pool_data}}',end_time='{{end_time}}')
)

and query 2283344 should be added to the repo as well. Note that all query parameters should be lower case for this to work. So this query and the underlying query need to change parameter names.

The resulting table could also be renamed to something like valid_vouches_with_names or something shorter.

[fhenneke]

This block should be replaced by something like

solver_slippage as (
    select * from query_3427730(start_time='{{start_time}}',end_time='{{end_time}}')
)

and query 3427730 should be added to the repo.

[fhenneke]

This table is really close to what query 4021306 does (see coincidence of wants query). With a bit of renaming, we could use

filtered_batches as (
    select
        ...
    from cow_protocol_ethereum.batches
    where ...
),
pre_batch_transfers as (
    select
        ...
    from query_4021306(start_time='{{start_time}}',end_time='{{end_time}}')
    where not transfer_type in ('slippage_in', 'slippage_out')
),
batch_transfers as (
    select
        ...
    from pre_batch_transfers
    join filtered_batches
)

[fhenneke]

This table and the parameter TokenList should be removed. They are not used anywhere. (The parameter also needs to be removed from the query in solver-rewards.)

[fhenneke]

Internalized imbalances are not user anymore, so this part of the query should be removed as well.

[fhenneke]

This is not the query used in solver-rewards and should be changed to 4017925.

The query also needs a time parameter and should be passed the start time of the accounting period.

 service_fee_data as (
    select
        solver,
        service_fee
    from query_4017925(cutoff_time='{{start_time}}')

[fhenneke]

NOW() should probably be changed to a cutoff_time parameter which would chosen as start_time.

[fhenneke]

The part on vouches might just reuse the vouches query.

[fhenneke]

That query does not look much simpler that just hard-coding all solver addresses, their starting date, and their status (e.g. exempt for 6 month, 9 month, indefinitely).

The query might help finding those dates.

[fhenneke]

(this query uses a different style (keywords in all caps) than the other query)

[harisang]

Closing as a lot of changes have happened in between so will reopen a PR with just the main dashboard there.
