First cut of telemetry integration.
Open telemetry can be enabled in two ways, first is via an opentelemetry java agent specified on the command line. With this way you get the advantage of spans created from other libraries, like hibernate. The java agent does byte code rewriting to insert spans.
The second way is with the open telemetry driver (that links with the opentelemetry sdk). This is a fat jar provided with this project and needs to go into the node drivers directory.
There was a mistake made when we first introduced notary request signature checking, in that we didn't wrap it in SerializedBytes so it always got deserialized as part of the flow message payload. So to check the signature, it has to be re-serialized. This means for cross-version compatibility we can never change the serialized format of NotarisationRequest. In this case we need make sure that every SecureHash mentioned in that data structure is a distinct instance, even if the values are repeated / identical, as that is how it was in Corda 1.
With the introduction of interning of SecureHash, this ceased to be true once again, including undoing the attempts to force it on the sending side that had been introduced in previous versions of Corda. So here we introduce a way to force it, and consolidate the forcing to distinct SecureHash instances in the NotarisationRequest itself, rather than leaving to the caller of the constructor to remember to do it, so that serialized form will always be as per Corda 1.
ENT-6947: Implement interning for SecureHash, CordaX500Name, PublicKey, AsbtractParty and SignatureAttachmentConstraint, including automatic detection of internable types off companion objects in AMQP & Kyro deserialization. In some cases, add new factory methods to companion objects, and make main code base use them.
Performance tested in performance cluster with no negative impact visible (so default concurrency setting seems okay).
Testing suggests 5-6x memory saving for tokens in TokensSDK in memory selector. Should see approx. 1 million tokens per GB or better (1.5 million for the tokens we tested with).
This commit ports the previously implemented fix from Corda ENT. Due to
the unrelated changes and merge conflict, the fix has been manually
copied rather than cherry-picked.
