v0.5.0

Added

• Python library and CLI tools for accessing Golioth REST API (scripts/python/golioth/)
• twister+pytest tests for samples/rpc/
• support for GOLIOTHCTL_CONFIG environment variable in pytest scripts
• GOLIOTH_CIPHERSUITES Kconfig option, which allows selection of preferred ciphersuites used
  during DTLS handshake (by default only one ciphersuite is selected to reduce DTLS handshake)
• configurable settings response length with GOLIOTH_SETTINGS_MAX_RESPONSE_LEN
• support for certificate-based authentication with coap.golioth.io in sample/hello/

Fixed

• handling of multiple desired firmware changes in samples/dfu/, which previously caused corrupted
  firmware upgrade
• infinite loop in ciphersuite negotiation during DTLS handshake, solved by narrowing down used
  ciphersuites by introducing GOLIOTH_CIPHERSUITES Kconfig option
• handling of CoAP observation notifications (used by observations in LightDB State, DFU desired
  firmware, RPC and Settings services) with specific (too high) CoAP observe sequence numbers, which
  resulted in ignoring incoming CoAP observe notifications
• disconnecting (and reconnecting) from Golioth server on nRF9160 based devices, which sometimes
  resulted in deadlock on socket close operation
• handling of CoAP requests when disconnected from Golioth server (sending/scheduling requests is no
  longer possible when disconnected and already scheduled/pending requests are cancelled once client
  gets disconnected)

Changed

• pytest tests for samples/logging/ use introduced Python library instead of goliothctl
• hardware tests use coap.golioth.dev (backend development version)
