99% of our usecases use Value[ContractId] so this PR just fixes it.
The few other usescases are:
1. Value[Nothing] which we use for keys. This is technically more
precise but we benefit very little from it.
2. Value[String] mostly because in a few places we are lazy.
We don’t have any code which benefits from being polymorphic in the
contract id type.

Because of some coupling we also have to upgrade Scalaz to the latest

The Scalatest changes are quite involved because the JAR has been broken
up into several smaller JARs. Because Bazel expects us to specify all
dependencies and doesn't allow transitive dependencies to be used
directly, this means that we need to specify the explicit Scalatest
components that we use.
As you can imagine, this results in quite a big set of changes. They
are, however, constrained to dependency management; all the code remains
the same.

Test that Daml ledger export script handles DALF packages in LF version
1.6. These packages don't contain metadata, meanint `--package` flags

type class instances, meaning the export script needs to contain newly

Daml script.

* Expose unconstrained Daml script commands
This will be used in Daml ledger exports of contracts defined in Daml LF
versions before 1.8. These versions did not include typeclass instances,
meaning that instances such as HasTemplateTypeRep need to be recreated
in the export Script. Not all instances required in the `Template t`
constraint can be recreated at the use-site. E.g. `HasSignatory`. By
avoiding these kinds of constraints it is possible to handle these cases
in Daml ledger exports anyway.

* Expose set of stable-packages package-ids
Needed in Daml ledger export to decide whether to depend on a package
without metadata or not.
changelog_begin
changelog_end
* Handle package dependencies without metadata in Daml export
This addresses the immediate issue reported in
https://github.com/digital-asset/daml/issues/10435.
DALF before LF version 1.8 don't contain metadata such as the package
name and version. However, Daml ledger export assumed that metadata was
available to generate `--package` flags for data-dependencies.
This change generates `--package=<hash>` flags for such dependencies on
packages that don't have metadata available.
This change requires additional care when checking if a package is a
stable-package. As the package name is not available without metadata we
cannot just check against names such as `daml-stdlib`. Instead this
change uses the list of stable-package package-ids exposed by
`com.daml.lf.language.StablePackages.Ids`, which was introduced in
0da814d250 (diff-208c6948c7c7f2b582faa8e4792bfe78b231188881947ad0cdd5046e0b9a40e7)
Note that this does not fully resolve#10435. Building a generated Daml
ledger export script will fail on missing instances of standard classes
such as `HasTemplate` because packages prior to LF version 1.8 don't
contain type-class instances. This will be addressed in a separate PR.

* It seems to origianl check more that nesting (and so to be
overcomplicate)
* It was used in non-consitent way. It was used to check create
arguments and choice arguments, but niether choice result nor
contract key.
CHANGELOG_BEGIN
CHANGELOG_END
The conversion of SValue to Value already ensures the resulting value
has a serializable type. Here we add a check to ensure it does not
overpass the maximum allow nesting.
* Limit length of package ids to 64 characters
In practice, you cannot use a package id that is not a valid sha256
outside of a test anyway since we validate them. However, we didn’t
enforce it at the daml-lf level which is a bit annoying.
This PR fixes this and adds a length restriction of 64
characters (i.e. 256 bytes for sha256).
We could go a bit further and also restrict the characters to valid
sha256 hashes (i.e. 64 character hex strings). I don’t feel all that
strongly about that either way. We use other characters in tests but
fixing that shouldn’t be particularly hard either. The extra
characters don’t seem to cause problem so far, so I think it’s fine to
keep that.
No changelog entry since I don’t see how a user can be affected by this.

Part of #9947, building on the key visibility checks from #10136
This PR adds a divulgence warning inside the traceLog.
I wasn't sure whether:
1. these warnings should be kept in a separate structure from the
traceLog, and therefore transmitted separately, or
2. these warnings should be kept together with traces, but the severity
should be tracked and also transmitted over grpc, and warnings should
be logged as warnings instead of as debug messages, or
3. these warnings should be kept together with traces, but
logged as warnings instead of debug messages,
4. these warnings should be treated exactly like traces
I'm leaning toward #2, but this PR implements #3.

* daml-lf/data: Truncate party names in log output, on request.
The party name can grow quite long, so we offer ledger implementors the
opportunity to truncate it in structured log output.
Unfortunately, because we use Logback through the global
`LoggerFactory`, there is no place to inject logging configuration. This
means we also need to use global, mutable state to configure logging
output. I have added a `LoggingConfiguration` class+object in Daml-LF
Data, which may not be the best place, but I can't think of a better
one right now. I suggest we leave it there until it has reason to grow,
at which point we may want to move it.
