Allow ability to adjust query ranges for EVM transactions

[LefterisJP]

Abstract

Once evm transactions are queried for a range, then they are no longer queried for this range again. Once queried and saved, we save them in the DB and update the queried range.

• For transactions:

  rotki/rotkehlchen/chain/evm/transactions.py

  Line 188 in 341b2ed

  self.dbranges.update_used_query_range(

• For internal transactions:

  rotki/rotkehlchen/chain/evm/transactions.py

  Line 295 in 341b2ed

  self.dbranges.update_used_query_range(

• For ERC20 token transfers:

  rotki/rotkehlchen/chain/evm/transactions.py

  Line 397 in 341b2ed

  self.dbranges.update_used_query_range(

This will make it so that next query of transaction data won't query the same range again. That's all good and intended.

But the problem comes when for some reason the remote source of data has problems and instead of failing with an error, returns wrong data. Or if for some reason some bug causes transactions on a range to be missed. At that point we need to do something.

We have the purge evm data functionality. So we can purge all transactions and ranges for a given chain. But that's a bit too heavy handed.

Adjusting the queried range so it requeries the last X days of data should also be possible.

Specification

• Create API to get, and adjust query ranges for anything.
• Expose it in the frontend in a user friendly way so that the user can adjust the queried ranges to fix the problem explained in the issue
