This annotation is native to Scala 2.12.13+ and 2.13.2+. It replaces
most usages of `@silent`.
I had to get creative about a couple of use cases that didn't work.
Specifically:
1. Suppressing deprecation warnings works, but Scala 2.12 erroneously
complains that the `@nowarn` is unnecessary. I had to suppress
this warning too with `-Ywarn-unused:-nowarn`.
2. I can't seem to suppress the warning, "The outer reference in this
type test cannot be checked at run time." Instead, I have
refactored the code to remove the warning.
We still need to use the silencer plugin to suppress some warnings about
unused imports (because of compatibility between Scala 2.12 and 2.13),
but this means we no longer need the library, and therefore it is not a
transitive dependency that downstream consumers need to worry about.

This is being pulled in anyway because of Maven/Gradle/etc's fun

depend upon transitively depends on Scala 2.12.13, so any downstream
consumers will see that as the Scala version required.
Bringing the Daml repo in line means no more confusion.

We need to add Oracle support to other components like the trigger

stomp on each other so this PR adds a fixture that generates a random
user (which also comes with its own schema, creating new databases is
a bit different in oracle) which we use testing.

It also clears up the confusing error around gatling and removes a
redundant dependency on sbt (no idea why we had that in the first
place) both of which resulted in Scala 2.12 dependencies in our 2.13
lockfile which is obviously bad.
With this, we should now be ready to publish Scala 2.13 artifacts once

we cannot fully preserve the rest of the config. I’ve made some

about any of the settings so happy to change them to something else.

This is necessary to at least attempt an upgrade to 2.13 and

import structure has changed and a bunch of things (primarily
scalacheck support) got split out.
Apologies for the giant PR, I don’t see a way to keep it smaller.

* resources: Move builders into //ledger/ledger-resources.
Keep the actual constructors in a trait, but instantiate it when working
with ledger code.
This allows us to later introduce an extra "context" type parameter to
ResourceOwner.
* resources-akka: Move the builders in to //ledger/ledger-resources.
* resources: Introduce an abstract `Context` parameter for owners.
This replaces the concrete `ExecutionContext`. While it _can_ be an
execution context, it really doesn't matter as long as we can get at one
somehow.
This is being introduced so we can wrap the context in a container,
either for type tagging or to include extra information.
Because our current context _is_ `ExecutionContext`, and an implicit is
provided to extract it, we can end up with two ways to get the same
value. We use shadowing to prevent this. This problem should go away in
the near future when a new context type is added.
CHANGELOG_BEGIN
