[#221] Expand xmlns field ignore

Signed-off-by: Marina Biryukova <m.biryukova@yadro.com>

CHANGELOG.md

@@ -45,6 +45,7 @@ This document outlines major changes between releases.
 - 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)
 - Apply placement policies and copies if there is at least one valid value (#168)
+- Generalise config param `use_default_xmlns_for_complete_multipart` to `use_default_xmlns` so that use default xmlns for all requests (#221)
 
 ### Removed
 - Drop `tree.service` param (now endpoints from `peers` section are used) (#133)
