Fix DDO: Stats and Prices for exchanges/dispensers

[mariacarmina]

Fixes #525 .

Changes proposed in this PR:

• Create type for IndexedMetadata
• Delete key when validating DDO & compose metadata hash
• Update logic for MetadataCreated, MetadataUpdated, OrderStarted, OrderReused
• Created new monitoring logic for ExchangeCreated, ExchangeActivated, ExchangeRateChanged, ExchangeDeactivated, DispenserActivated, DispenserDeactivated
• Fixed hardcoded service[0].datatokenAddress when inserting the DDO in the DB -> you can have multiple datatokens attached to the same NFT with different services
• Add new util function to return service id based on datatoken address
• Create util function which returns the ddo updated with according stats
• Fix bug in getEventData -> when decoding the event, by default it is retrieved first log's topics, logs[0].topics, if the tx receipt contains multiple events, those are not captured automatically -> fix: check for each log if topic[0] matches one value from EVENTS_HASHES.
• Add tests w bundled txs for indexedMetadata stats

I'll put this in review to see if for Metadata events and Order events, I implemented as expected on the specs.
Still FixedRateExchange and Dispenser events needs to be monitored (WIP) along with tests for fixed rate exchange & dispenser pricing schemas.
