Add LDMS_STREAM_EVENT_CLOSE

Due to the asynchronous nature of `ldms_stream`, a stream event may
already in the process of being delivered to the application callback
function at the same time that the application closes the stream client
and releases application's resources associated with it. This results in
a use-after-free.

This patch adds `LDMS_STREAM_EVENT_CLOSE` callback event that is
delivered to the application callback function when the stream client is
closed. The `LDMS_STREAM_EVENT_CLOSE` is the last event to be delivered
to the client call back function, so that the application can then
safely release resources asscoiated with the stream client after
receiving it.

OVIS Release 4.4.1

This is the release tag for OVIS-4.3.11

Principle features in this release:
* OVIS Log Library
* Sampler Base Support for slurm2 sampler
* Avro-Kafka Store
* Moved all samplers to their own subdirectory
* Various scalability and resiliency improvements

LDMS Release 4.3.10

LDMS 4.3.10 remains binary compatible with OVIS 4.3 releases back to
OVIS 4.3.3

If you are storing data from the the new samplers that use lists
and records, please do so with a storage decomposition configuration.
Storing these metric sets (procstat2, procnet2, slurm2, ...) without
a decomposition configuration can lead to confusing results.

There are 78 commits in this release that add new samplers and
include many scalability and resiliency improvements.
