whether netdata runs from within a kubernetes pod, or directly on the host machine. (#9303)
Fixes #8044
Ensures we get consistent kubernetes cgroup container names, regardless of whether netdata runs from within a kubernetes pod, or directly on the host machine.
Additional Information
Fixes a bug that was originally fixed in #6885 and re-introduced in #7416.
Fixes the seemingly non-functional selector in #7416

This PR adds (inactive) support that we will use to fill the gaps on chart when a receiving agent goes offline and the sender reconnects. The streaming component has been reworked to make the connection bi-directional and fix several outstanding bugs in the area.
* Fixed an incorrect case of version negotiation. Removed fatal() on exhaustion of fds.
* Fixed cases that fell through to polling the socket after closing.
* Fixed locking of data related to sender and receiver in the host structure.
* Added fine-grained locks to reduce contention.
* Added circular buffer to sender to prevent starvation in high-latency conditions.
* Fixed case where agent is a proxy and negotiated different streaming versions with sender and receiver.
* Changed interface to new parser to put the buffering code in streaming.
* Fixed the bug that stopped senders from reconnecting after their socket times out - this was part of the scaling fixes that provide an early shortcut path for rejecting connections without lock contention.
* Uses fine-grained locking and a different approach to thread shutdown instead.
* Added liveness detection to connections to allow selection of the best connection.

* Update eBPF install to use released version.
This updates the install code for the eBPF plugin to properly utilize
(and verify) a tagged release of the plugin instead of pulling the
upstream master branch.
It also adds support for using a local copy of the tarball, and switchs
the default behavior to install the eBPF plugin instead of not
installing it.
