[ImageMosaic] Add "recalculate/uploadBBox" to add_granule function

[apparell]

Is your feature request related to a problem? Please describe.
It's not possible to add "recalculate/uploadBBox" parameter to an harvest granule request.

Geoserver doc: https://docs.geoserver.org/latest/en/user/rest/api/coveragestores.html#rest-api-coveragestores-file-put (recalculate in POST request at /workspaces//coveragestores//file[.<extension])

Geoserver API Swagger: https://docs.geoserver.org/latest/en/api/#1.0.0/coveragestores.yaml (uploadBBox in POST request /workspaces/{workspace}/coveragestores/{store}/{method}.{format} )

Describe the solution you'd like
Add parameters in "add_granule" function to be able to recalculate the BBox of the ImageMosaic once updated.
In line 648 of catalog.py there's the function "add_granule" with declared parameters in line 666 as "params = dict()"; unfortunately there's no function argument to pass key:value pair to the dictionary.

Describe alternatives you've considered
None at the moment.

Additional context
E.g. I have an ImageMosaic over a ROI (a Polygon) with time attribute. When updating Polygon coordinates it triggers a new elaboration of the area and then post the resulting raster to Geoserver. Since orginal Polygon coordinates were updated, the new elaboration will have a different BBox than the original ImageMosaic (assuming that for example new area is larger than the previous and bbox is inferred from data).
