Previously, ParseCmdLineArgs was the function directly wrapping the
ceph rados_conf_parse_argv function. This function has the improper
(IMO) behavior of assuming you didn't know your own argv[0] and just
always stuck "placeholder" in argv[0]. This function adds a more
direct wrapper ParseConfigArgv that allows the caller to pass an
full argv, and they can put any placholder value desired if they want.

In order to avoid external dependencies on implementation details,
this change replaces RadosError with the unexported radosError. In case
some application really needs access to the integer value, it can use
the pattern
var errno interface{ Errno() int }
if errors.As(err, errno) { ... errno.Errno() ... }

Organize the rados package a bit more by moving functions that wrap
rados_xyz_command functions into a dedicated file. Move related test to
a separate file as well.

For more consisistency use getError where possible.
Changes produced using `gofmt -r 'RadosError(int(x)) -> getError(x)`,
followed by a few manual fixups.

The cephfs function ceph_create_from_rados requires the cluster_t
value, which is current private to the Conn type. Alias the cluster_t
type and allow other pkgs to get it if needed.

A number of the error handling checks do not seem to need to check
for specific non-zero error returns so we should be able to
convert to getRadosError rather than a lot of boiler-plate.

A number of the functions in rados do not use the simple error
conversion function where is obviously applies. Convert them to use it.

Release resources that are allocated while configuring the connection to
the cluster. rados_shutdown() should only be needed after a successful
call to rados_connect(), however if the connection has been configured
with non-default parameters, some of the parameters may be allocated
before connecting. rados_shutdown() will free the allocated resources,
even if there has not been a connection yet.
Note that the finalizers get executed during garbage collection, which
can be forced by calling runtime.GC() for testing.
