The checked exceptions will force the caller to explicitly deal with any errors that may occur during a Sources request call. The goal of this is to force the developer to think about which actions should be taken when the external service is reporting errors.

The reason for this change is that the "get endpoints" endpoint was reporting 404 errors when at least one endpoint had references to non-existing Sources secrets. In theory this should not happen, because we already took good care of making sure that every operation leaves the Sources references as they should in the RHCLOUD-24435 ticket.

However, there are a couple of "unlikely" scenarios in which this may happen:

• The secrets dissapear in Sources for any unexpected reason. One of them could be, for example, a bad data migration on their side.
• QE tests may spawn two Sources instances, and this could make some tests fail if they end up creating secrets with cross references to those instances.
