Document optional flags for generate-partitions command

[nehanene15]

The generate-table-partitions doesn't make use of the cli_tools function add_common_arguments() and instead duplicates efforts to make its own _add_common_partition_arguments. Due to this it lacks support for certain common flags, such as '--config-file-json'.

The documentation for this also needs to be updated - none of the optional flags (filter-status, bqrh, etc) are documented.
