[FEATURE] include option to parse overwrite flag to spark submit

[jeppe742]

Description

One of the default arguments to all our spark jobs is the --overwrite flag.
This is mainly used for the few places we have jobs that do incremental loading, to fully reload all historical data.
(e.g https://github.com/SneaksAndData/shrek/blob/93dc85842f55434bd82029360284148cc7980513/shrek/kits/generalized/copy_data_merge_by_key.py#L161)

However, currently it's not possible to specify this argument when submitting a beast job using the CLI, using the --overrides .
Instead you have to manually change the CRD, or create a new one

Possible solution

Allow one to specify the overwrite flag in the --overrides argument
