conntrackd: add `DisableExternalCache' clause
This patch adds the clause `DisableExternalCache' that allows you to disable the external cache and to directly inject the entries into the kernel conntrack table. As a result, the CPU consumption of conntrackd increases. This clause can only be used with the FT-FW and the notrack synchronization modes, but not with the alarm mode.

+ # This clause allows you to disable the external cache. Thus, the

+ # table. As a result, you save memory in user-space but you consume
+ # slots in the kernel conntrack table for backup state entries.
+ # Moreover, disabling the external cache means more CPU consumption.
+ # You need a Linux kernel >= 2.6.29 to use this feature. By default,
+ # this clause is set off. If you are installing conntrackd for first
+ # time, please read the user manual and I encourage you to consider
+ # using the fail-over scripts instead of enabling this option!
