Subject: common/tracer: set the tracer provider singleton
X-Git-Tag: v18.0.0~92^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=9362be0fd2139528165dc176efe5d55f67b2bb1a;p=ceph.git

common/tracer: set the tracer provider singleton

due to changes in opentelemetry lib, the destruction of the tracer provider at the end of the init method also destructs the tracer, so we need to keep the tracer provider, as mentioned in opentelemetry documentation
