trace_record is used to poll the spdk trace shm file
and store new entries from it to another specified trace file.
This could help retain the trace_entires from the overlay of
trace circular buffer
Note:
* trace_record reads the input tracefile into a process-local
memory and writes trace entries to the output file only at shutdown.
* trace_record can be shut down on SIGINT or SIGTERM signal.
A usage sample is:
./spdk_trace_record -s bdev_svc -p <spdk app pid> -f trace.tmp -q

This RPC doesn't really work in some cases - for example,
trying to delete one NVMe namespace bdev from a controller
with multiple namespaces, or just one virtio SCSI device
from a virtio-scsi controller. We've previously kept it
and marked it as "debugging only" - but every bdev module
has its own RPC method now for deleting what it constructed,
so keeping the generic delete_bdev RPC is asking for
trouble in some of the cases mentioned above. We'll remove
it in the 19.04 release.

When the caller of the RPC API has all the necessary information about
how to access a Ceph cluster, then having to create configuration
files before calling the RPC API is problematic (has to touch files
owned by a local admin, changes must be removed again).
But having to encode support for certain configuration options in SPDK
is also problematic, because that might change depending on the
librados version.
The approach taken here is to merely pass through arbitrary key/value
config options. Existing config files are ignored when that happens.
The caller of the RPC then has full control over the connection setup
and can be sure that he does not inherit settings from a local file
accidentally.
In addition, user management is supported now, with or without a
config. This is useful for accessing a volume with a less privileged
user. Previously, passing NULL to rados_create implicitly chose the
"admin" user.
