Integrate reputation_tracker with hivemind

Requires: reputation_tracker!11 (added option to change if app is forking and attached on setup)

Changes:

1. Added reputation_tracker as a submodule and integrated with hivemind sync,
2. Removed reputation and is_implicit columns from hive_accounts, hive_reputation_data table removed,
3. Adjusted hive_accounts_view to supplement data from reputation_tracker:

• join on context.accounts_view (convert_haf_id is not enough in certain scenarios like in CI - mock data moves some accounts in hive_accounts and there is a slightly bigger slip between hive.accounts and hive_accounts)
• context is specified in this view, I think it can stay that way untill the python server gets completly replaced by postgrest and this issue with hivemind not supporting custom schema will be resolved,

4. Adjust test (condenser, bridge, tags api):

• blocktrades pattern changed to "author_reputation": 69.12 (from "author_reputation": 68.63) - previous value was incorrect (tested and compared with reputation from reputation_api.get_account_reputations)
• additional "reblogs": 0 in response (I think it should be there?)
• order changed to "reblogs": 0,"replies": [] (from "replies": [],"reblogs": 0) (I think it doesn't matter)
• in condenser api most tests return list of accounts with their reputations so there is much more changes
• the same in tags_api - only reputation changes

5. join_collapse_limit from 1 to 6 - improves performance of joining reptracker's tables
