Context:
If the user changes some of the report configuration that are version/definition dependent (variables/flow nodes), we currently reset that configuration to default. This is inconvenient for the users, because if they apply a configuration and then switch the version on their report, they lose all the configuration they applied.

This currently happens on the following configurations:

• hiding columns - raw data reports - OPT-4913
• reordering columns - raw data report - OPT-4914
• process part - process instance report - OPT-4915
• target value - flow node heatmap report - OPT-4916
