Merge #10901: Fix constness of ArgsManager methods
a622a1768 Fix constness of ArgsManager methods (João Barbosa) Pull request description: Make `cs_args` mutex mutable so that const methods can acquire it. There's also tiny performance improvement by avoiding two map lookups when retrieving an argument value.
