Show transaction prices

[gabrielmatei]

Reasoning

• besides value, a usd price would be very helpful to be attached to the transaction operations, so that in situations like metabonding claim rewards, a total usd value of the claimed rewards can be estimated

Proposed Changes

• remove dependency to data.elrond.com
• use the plugin to extract token prices, which internally fetches historical price information.
• ESDT prices are supported only for the tokens listed on xExchange and Jungle DEX

How to test

• /transactions?function=claimRewards&withOperations=true should return valueUsd for each operation with supported tokens
• /transactions/:txHash should return valueUsd for each operation with supported tokens
