Option to provide a summary id parameter in the transaction API

Purpose/Overview:

To resolve MODFISTO-260, batch transactions cannot be linked with the order id / invoice id anymore. So we need to pass an additional parameter, the summary id, for POST/PUT transaction calls.

Also, since transaction summaries are not using order or invoice ids as the key anymore, they are unique and should not need to be modified, so we can deprecate PUT for transaction summaries (there might be a need for that for troubleshooting which we will have to check, but this can be done later).

Requirements/Scope:

1. Add optional transactionSummaryId query parameter for the following:
   POST /finance-storage/transactions
   PUT /finance-storage/transactions/{id}
2. The following should be deprecated:
   PUT /finance-storage/order-transaction-summaries/{id}
   PUT /finance-storage/invoice-transaction-summaries/{id}

Approach:

Update ramls/transaction.raml and ramls/transaction-summary.raml.

Use the new summary id instead of the order id or invoice id as the key for transaction summaries.

Acceptance criteria:

• Match requirements
• Update unit tests

Update:
I had to go beyond this scope in order to use the new summary id, and implemented most of the needed changes in MODFISTO for MODFISTO-260. Given the scope change I postponed the PUT summary deprecation.
