Alarm management: ietf-alarms YANG module for sysrepo

With this daemon, sysrepo applications can implement the ietf-alarms YANG module from RFC 8632. As an app developer, you simply:

• create the required alarm identities based on al:alarm-type
• provide the list of possible alarms
• execute an internal RPC each time an alarm event occurs

This daemon takes care of the rest:

• alarm shelving
• alarm summaries and statistics
• alarm notifications
• alarm history

The following optional features are currently not implemented (patches welcome):

• alarm profiles and severity assignment
• relations, which includes root cause analysis, impacted resources and alarm correlation
• operator actions

Dependencies

• libyang-cpp - C++ bindings for libyang
• sysrepo-cpp - C++ bindings for sysrepo
• C++20 compiler (e.g., GCC 10.x+, clang 10+)
• CMake 3.19+
• Boost 1.78+ (header-only is sufficient)
• pkg-config
• spdlog
• fmt - C++ string formatting library
• date for time zones handling
• docopt for command line options
• doctest for unit testing
• trompeloeil for unit testing
