Subject: tools/kvstore_tool: add "std::" before ostream and string
X-Git-Tag: v17.1.0~1436^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F42235%2Fhead;p=ceph.git

tools/kvstore_tool: add "std::" before ostream and string

also use <iosfwd> instead of <iostream> for forward declaration of
std::ostream, so that we don't need to include the whole iostream
header file in kvstore_tool.h.
