* Started on reimplementing the SimTrace implementation

* updated trace format. Fragments now do not have a deadline, but a duration. The Fragments are executed in order.

* Revamped the trace system. All TraceFormat files are now in the api module. This fixes some problems with not being able to use types of traces

* applied spotless

* Updated all package versions including kotlin. Updated all web-server tests to run.

* Changed the java version of the tests. OpenDC now only supports java 19.

* small update

* test update

* new update

* updated docker version to 19

* updated docker version to 19

This change adds the log4j-core dependency to various modules of OpenDC
using log4j2, to ensure logging keeps working. The upgrade to SLF4J 2.0 broke
the Log4j2 functionality, since the log4j-core artifact is not
automatically shipped with the SLF4J implementation.

This change updates the build configuration to use Spotless for code
formating of both Kotlin and Java.

This change updates the repository to remove the use of wildcard imports
everywhere. Wildcard imports are not allowed by default by Ktlint as
well as Google's Java style guide.

This change updates the trace API by introducing a limited type system
for the table columns. Previously, the table columns could have any
possible type representable by the JVM. With this change, we limit the
available types to a small type system.

This change adds a command line interface for querying workload traces
using SQL. We provide a new command for the trace tools that can query a
workload trace.

This change moves the trace conventions (such as table and column names)
in a separate conv package, so that it is separated from the main API.
This also allows for a potential move into a separate module in the
future.
