Implement resource usage report

Feature Request

Using the Blockifier, we can get the resource used for invoke transaction invocations.
Would be great to have a flag --resource-report to print out resources used (steps, built-ins etc)

Thank you for the request. We are definitely considering adding transactions profiling at some point.

This should be considered as well on cairo level - which could enable users to assert gas consumed from a test.
I.e. a contract invocation would return gas consumed.

Also i think we should profile on transaction level and as well sum the transactions gas for a whole test (if a person wants to know the whole flows' cost)

We could start by implementing it for a single test case as a whole as it will be the simplest.

Later we could try to do it on a transaction level maybe something like this

let call_info = CallInfoDispatcher.get_balance()
assert(call_info.gas_usage < 100000, `above expected gas usage`)
assert(call_info.value == 5, `incorrect value`)

Wouldn't it be better to have step counts rather than gas usage?

[MaksymilianDemitraszek]

@enitrat Sure but steps are only part of the picture as builtins can impose significant cost as well. Ideally we should report:

• steps
• builtins usage
• estimated gas

yes, indeed, I just wanted to make sure we were not talking about Sierra Gas (I'm still not sure it's actually mapped to "real" execution resources)

#362 Should be taken under consideration
