Add support for running iRODS server with Address Sanitizer enabled

Enhancement

The core test suite and unit test suite are the best candidates for generating a report of memory leaks in the iRODS server. Having this information allows the core dev team to resolve the memory leaks and improve stability of the server.

The following requirements must be satisfied to make this work:

• Install the externals package for the Clang compiler
• Add environment variable for llvm-symbolizer
  • export ASAN_SYMBOLIZER_PATH=/opt/irods-externals/clang13.0.0-0/bin/llvm-symbolizer
• The testing environment must gather the output files or perhaps leak containers
  • /tmp/irods_asan_output.<PID>
• Figure out how to handle leaks reported by the icommands
  • If leaks are reported, the python tests will fail due to the exit code and unexpected output

The plugin tests could also grow support for this as well.
