Description of problem:

The column management code stores user selected columns and their ordering in browser local storage. This is beneficial so that settings are remembered.

However, if a table gets additional columns, the outdated local storage is preventing those new columns from showing in the selection modal.

Version-Release number of selected component (if applicable):

Probably dates back to first delivery of column management feature.

How reproducible:

Always

Steps to Reproduce:

1. Visit virtual machines list at /multicloud/infrastructure/virtualmachines
2. In browser local storage, edit values to include only a few columns.

Actual results:

Only the columns listed in local storage are shown in the table and modal.

Expected results:

Column managed code should add any columns not listed in the local storage to the end of the list and then update local storage accordingly.
