Write a test script that checks status of each agent

[trentmc]

From Alex in slack:

I'm using this query for general overview on subgraph:

query{
  predictContracts{
    id
    token{
...

Based on this, we can write a test script that:

• check if we have all predictoor contracts
• checks if predictoor 1 & 2 have predictions on at least 90% of the last 24 slots (two hours) for all pairs
• checks if predictoor 1 & 2 have less then 5 unclaimed revenue
• checks that we have at least 98% truevals submitted on last 24 slots
• checks that df-buyer has at least 10 buys (TBD) in the last two hours
• each pdr-trader has at least one valid subscription
• pdr-websocket has a valid subscription for only one pair

Suggestion: check OCEAN and Rose balances of test accounts
