Support for dynamic node creation

[yarnabrina]

Do Elyra support creating nodes in runtime?

For example, we have a component that splits the data into groups as provided in configuration (passed as input file or environment variable), and do some processing on those independently of one another. The number of splits is not known beforehand.

Earlier we were handling this with kfp.dsl.ParallelFor, by iterating over an output file. Does Elyra have any alternative to this?
