Zuul will execute bwrap with --disable-userns set if two conditions
hold. 1) The version of bwrap is 0.8.0 or newer and 2) User namespaces
are enabled in the zuul-executor runtime context. Doing so will
prevent the zuul-executor bwrap runtimes from creating additional
user namespaces which fortifies Zuul's security position.
