[#175] Use gate owner as object owner

This is required because node check session token owner
TrueCloudLab/frostfs-node#528
For client cut TrueCloudLab/frostfs-sdk-go#114
such owner will be gate owner

@@ -35,6 +35,7 @@ This document outlines major changes between releases.
 - Use default registerer for app metrics (#155)
 - Use chi router instead of archived gorlilla/mux (#149)
 - Complete multipart upload doesn't unnecessary copy now. Thus, the total time of multipart upload was reduced by 2 times (#63)
+- Use gate key to form object owner (#175)
 
 ### Removed
 - Drop `tree.service` param (now endpoints from `peers` section are used) (#133)
