EVM-779 Debug Transaction endpoint - throttling

[igorcrevar]

Description

Implement throttling for debug (transaction) endpoint(s). There should be some limit of number of requests per seconds allowed for those.
By default this limit is set to 5. It can be changed by --requests-per-second-debug server flag

This functionality has been added because debug endpoints are heavy in processing/memory consumption and that can lead to node crashing. By implementing throttling, clients can limit the frequency of these resource-intensive calls, helping to ensure the stability and uptime of the node.

Changes include

• Bugfix (non-breaking change that solves an issue)
• Hotfix (change that solves an urgent issue, and requires immediate attention)
• New feature (non-breaking change that adds functionality)
• Breaking change (change that is not backwards-compatible and/or changes current functionality)

Manual tests

Start cluster, deploy smart contract(s) and transaction that calls some of those sc. 0x09e60436fc2344c03ef2c721dcb179d2e9cb4cecf535f1217f25abe24ea37dc6 is hash of that transaction and that is the tx you want to debug.
Try to execute following endpoint request more than five times. First five times you should retrieve answer, sixth time you should retrieve error.
