Changes

releng: use simrel versions of lsp4j in master and e4.20 target

Update both master and e4.20 targets for that. Use Guava 30.1.0 since
it's required by updated lsp4j version.

Update source code to adjust to updated APIs in lsp4j.

Don't implement method that provides the same implementation in the
default implementation of interface.

Change deprecated API setting to warning.

server: Use new API to detect experiment types in the trace server

With this it's possible to automatically detect the experiment type and
instantiate the corresponding experiment class that extends
TmfExperiment.

Using this API, custom experiment types can provide custom logic when
running in the trace server.
