DAML Ledger Integration Kit

Move to asynchronous package management service. ResponseMatcher is not needed and uploadPackages now returns SubmissionResult See #3806
Fix indexer crash on duplicate submission. See #3847
Standardize and cleanup metric names to use underscores that are compatible with Prometheus
StandaloneAPiServer rather than StandaloneIndexServer
Config class needs to be defined in ledger implementation and is no longer available from platform
Add FailingCommandsIT and CommandSubmissionCompletion to Ledger test tool suite. Some of the tests previously part of the CommandService Ledger API Test Tool suite have been moved to a new home in CommandSubmissionCompletion to reflect the fact that those use the submission/completion workflow instead of leveraging the submit-and-wait alternatives.

DAML Triggers - Experimental

Fix and document /contracts/lookup endpoint. See #3755.
Expose exercise result. Changed the output of the /command/exercise. Note exerciseResult and contracts in {"status":200,"result":{"exerciseResult": ...,"contracts":[...]}. See #3314.

As of 0.13.39, we merged a number of internal JAR files in the SDK tarball to reduce its size. These jars used to be standalone JARs you could invoke as e.g. java -jar sandbox.jar <args>. As a result of merging the jars, they lost their individual logback.xml configuration file. Although running the jars directly was (and is still) not supported, note that you can now achieve the same behaviour with e.g. java -Dlogback.configurationFile=sandbox-logback.xml -jar daml-sdk.jar sandbox <args>.

Fix an issue where transitive package dependencies resulted in packages not being found, if the DAR name was changed with -o.
