Add support for getting the alignment (stripe size) in bytes for pools that require/support it.
Fixes#739
This commit adds two new API calls to IOContext, one to know if the pool requires alignment and
the second one to get the stripe size in bytes:
RequiresAlignment() (bool, error)
Alignment() (uint64, error)

Because we have a finalizer configured for Conn that cleans up Ceph
resources, it's important that we don't let it get GC'd before anything
that depends on it has been cleaned up. Since clients are free to hold a
reference to an IOContext without maintaining a reference to the
underlying Conn, we hold such a Conn reference within the IOContext to
signal this dependency to the Go GC.

Previous changes added support for operating on omap keys that include
null characters (e.g. rados_omap_get_next2,
rados_write_op_omap_rm_keys2). This change adds some basic test
coverage those operations' null character support.

The previous `rados_nobjects_list_open` used for listing could not
return oids that included null characters. Although this isn't a common
case, having go-ceph able to list such objects is useful for bugs such
as https://tracker.ceph.com/issues/48874.

WriteOp.RmOmapKeys now uses rados_write_op_omap_rm_keys2().
The entirety of removeOmapKeysStep struct was removed as it's not necessary for
it to own the various C-allocated values passed to
rados_write_op_omap_rm_keys2() as arguments. rados_write_op_omap_rm_keys2()
makes copies of all the string-based args [1], so it's sufficient for them to
be short lived.

This change implements the bindings for the watch/notify APIs of
librados. Instead of callbacks, the watcher is implemented with more
Go-idiomatic channels. A watcher object exposes two read-only
channels, one to receive the notify events and one to receive
occuring errors.

We no longer support ceph luminous, and have not for a while. This
test case was kept separately from the others because it didn't function
correctly when tested against luminous clusters. As part of the effort
to remove the unsupported build tags, there's no longer even a reason
to keep this as it's own file with the tags removed, so merge it
together.
