Integration Test - Non standard transaction, but not invalid being anchored

[ASuciuX]

A transaction that normally wouldn't be picked by miners is picked and anchored by a miner. The only type of transaction like this is a transaction without fees (which won't get to mempool, but can be anchored by the miner directly).

Steps:

1. create transaction with 0 fees, signed
2. as miner, anchor it
3. check for any unexpected behaviour

Also, what are the limits in size of a transaction? Same as the block?

Optional: Check for possible reasons for dropped_problematic if those can be "mined" and chain will still continue?

Optional: RE Radone: get data from 0 (genesis) block in Clarity.

[ASuciuX]

Limits for block and for transactions are tested.

Problematic transactions are tested here.
