Send eth_getBalance requests from archive blocks to tracing node endpoint

[vbaranov]

Currently, all eth_getBalance requests, no mater whether latest or block number tag, are sent to JSON RPC endpoint (ETHEREUM_JSONRPC_HTTP_URL), which is not required to be archival in general.

We should send eth_getBalance requests to archival node endpoint (ETHEREUM_JSONRPC_TRACE_URL), when blocks are far from the head of the chain. Probably, need to create a param, which defines the number of blocks from the head of the chain, to consider them non-archival.
