Update QA service for DS [ECR-3586]: (#1224)

1. Added an ability to set key pair in TransactionMessage.Builder, so that the builder with a _set_ key pair can be passed around. #signedWith(keys) is provided to just set the keys (then can be followed by any other setters and completed with #build); #sign — as a shortcut to builder.signedWith(keys).build().

2. Added a Testkit#port method returning the TCP port on which the server providing service transport listens

3. Added a system-time provider for cases when the tests don’t need to control the current time.

4. QA service:
    1. Removed conversion of transactions into JSON, as it is no longer supported by the core.
    2. Removed conversion of transactions into RawTransactions
    3. Removed usages of RequiresNativeLibrary as it is no longer used in filtering
    4. Removed operations submitting a self-signed transaction except the two enabling Node testing. The rest of transactions shall be submitted through the usual channel.
    5. Moved transaction decoding tests to the transaction converter.

5. Add BOM to build scripts
