Implement the `cp` cmd from/to CSP storages

Now, sdfs-util can copy from/to the local machine. It'd be great to implement other storages (GC, Azure, AWS, IBM).

So that the command will look like this:

sdfs-util --seismic-dms-url {SEISMIC_DMS_URL} --client-id {CLIENT_ID} \
    --client-secret {CLIENT_SECRET} \
    --refresh-url {REFRESH_URL} \
    --refresh-token {REFRESH_TOKEN} \
    --csp-storage-options "{\"some_option\": \"some value\"}"
    cp gs://osdu/osdu/test.segy sd://osdu/osdu/test.segy
