Describe the bug

Currently the only way to use plugins in the API server is by injecting them via code that one has to actually write instead of just providing a declarative config file stating which plugins should be imported.

This fix is not possible until webpack/webpack#11316 gets merged and released.

In theory the changes to apply the fix are already part of the v0.2.0 release, but this issue has to stay open until we confirm the effectiveness of the fix via automated tests as well. (which also means that to close this, said tests have to be added also).

To Reproduce

  1. Write a config.json file that imports any plugins,
  2. start the API server while passing in the config.json file as the config file path and then
  3. watch it crash and burn because the runtime plugin imports are failing.

Expected behavior

Plugin imports at runtime work just as well as injection from code.

Literally any plugin will cause the mentioned crash.

Additional context

Been having a hard time convincing the webpack maintainers to accept the proposal so if you have a second, please head over there and support it with a thumbs up reaction or similar => webpack/webpack#11316

fix(api-server): runtime plugin imports
85e04ee 
- Upgrades webpack to the version[1] of it that
supports the webpackIgnore magic comment
for require calls not just for import calls.

- Adds a dedicated test package for the API server
which is necessary because that's how we can
verify that not just the Typescript compilation
output (./dist/lib/.../*.js) files but also
the webpack bundles are good when it comes to
runtime plugin importing.
Why? Because only when importing from another
package will the bundle be used so the local
test cases inside the cmd-api-server package
directory could not verify this particular
edge case.

[1]: This version is not yet officially released
becaue the PR for it has been stuck without review
since August 2020 so for now the workaround for
that is to specify the webpack version as the
direct commit reference on the fork that has the
required enhancements for this issue to be resolved.

Fixes hyperledger-cacti#346
