Which issue(s) this PR fixes (optional)
Closes # pb-4579

Special notes for your reviewer:
Added minor fix in the kopia source, to make sse-type as optional.
Before Fix:

cmd.Flag("sseType", "SSE types, only SSE-S3 is supported.").Required().StringVar(&c.s3options.SseType)

After Fix:

cmd.Flag("sseType", "SSE types, only SSE-S3 is supported.").Default("").StringVar(&c.s3options.SseType)

Will add the test result in the Px-backup PR and will add a reference to it.
