lib: dependency updates

[edsiper]

• Many libraries/dependencies have been updated to use CMake >= 3.20
• Added a new CMake option FLB_KAFKA to control globally if Kafka library should be included, this has a higher order of precedence compared to FLB_IN_KAFKA and FLB_OUT_KAFKA (default: FLB_KAFKA On)
• Centos 7: Kafka support has been disabled: librdkafka requires updated OpenSSL that is not available in Centos 7.
• Packaging: the following packages have been disabled:
  • Ubuntu 16.04
  • Ubuntu 18.04
  • Ubuntu 18.04 Arm64
  • Ubuntu 20.04
  • Ubuntu 20.04 Arm64
  • Raspbian Buster
  • Raspbian Bullseye

This change requires changes in run_code_analysis.sh script, because lpenz/ghaction-cmake:0.19 docker image (https://hub.docker.com/r/lpenz/ghaction-cmake) used in that script contains older version of CMake:

$ TEST_PRESET=valgrind SKIP_TESTS='flb-rt-out_td flb-it-network' ./run_code_analysis.sh
