PoC: using local abstractions sources instead of packages

[Yury-Fridlyand]

Abstractions lib sourceshttps://github.com/[opensearch-project/opensearch-net-abstractions](https://github.com/opensearch-project/opensearch-net-abstractions) were copied into .net client to use in tests. No need any more to store local nuget packages of abstractions, release them or worry about outdated/broken references to them.
Few fixes were made to let workflows pass.

In case if this approach approved this PR should be merged to upstream/main after closing opensearch-project#51.

Process-wise, this looks like a major improvement.
