[asan] improve asan success rate, kerberos context init and destroy

kerberos's init context is global, KinitContext* g_kinit_ctx,
it used new operator, but no delete operator.
It release the memory by os when program stopping.
Some asan tests may failed, when MiniCluster restart/stop.
KinitContext should be deleted safely.
