Make COG download metadata by default

[offtherailz]

Description

This option is necessary to allow zoom to layer and to get the data projection (see #9589 )

The reason why it was optional was because for big geotiffs it can take minutes.

We can overcome to this problem by:

• Allowing to preload this data in catalog add/edit form. Because this takes a long time, a botton should allow it (with the option to cancel), and this information will be saved in the catalog, among the records. This means that also the UI with the URL(s) may need a revision, probably with a list of records, or we may have undefined behaviors when we edit URLs.
• Store the data in the catalog so they do not have to be reloaded anymore. The user will have to refresh the metadata in catalog to reload the metadata and re-save if something changes.
• Store these data in the layer too, so they will be available for

The metadata stored in layers/records should provide at least data about:

• data projection and bbox
• bands

These data can be refreshed for the styling tool (or if was not originally saved)

support for bands is already captured by #9588 therefore all related aspects should be reported there and worked separately.
