In times of mempool congestion, txs can get on-chain with a significant delay.
Implementation details
Use transactions/getFee node's endpoint to calculate the fee for a tx passing tx's size and time (1 minute) to get on-chain as parameters.
Add max_tx_fee to the oracle config and use it as an upper limit for the suggested tx fee from the node. Set it to double the oracle config's base_fee initially.
I suppose that 'base_fee' can be dropped and tx fee from node used everywhere.
