policer: don't compute CPU clock frequency for each API call

In some virtualized environments, where we can't get TSC from
clib_get_cpuid, os_cpu_clock_frequency can take more than 1ms
to return. As the TSC value is invariant over time, it can be
cached in policer_init instead of being recalculated everytime
a policer is created/updated.

Type: improvement
