Autosubmit as workflow manager

#177 (closed)

This development changes several parts in Compute() and Collect(), including:

• ByChunks() to be renamed to ByChunks_ecflow(), and ByChunks_autosubmit() is created
• Compute() consider two cases: autosubmit or ecflow
• Collect() becomes a wrapper of Collect_ecflow() and Collect_autosubmit()
• inst/chunking/ to have subfolders Autosubmit and ecFlow
• new Compute() cluster components for Autosubmit

The tested cases: https://earth.bsc.es/gitlab/aho/aho-testtest/-/blob/master/startR/autosubmit/test_autosubmit.R

• Basic Start() call, function returns data without processing
• Basic Start() call, function calculating WeightedMean, attributes used
• Start() call with 2 dats, function calculating WeightedMean, attributes used
• Start() call with transform, function calculating WeightedMean, attributes used
• Basic Start() call, return 2 outputs with names (mean and min)

TODO:

• Change TODO parts
• Check resource usage (core/processor/threads)
• Documentation
