Add MetaRouter feature to RB4011iGS+RM/5HacQ2HnD

RB4011iGS+RM/5HacQ2HnD has 4 cores with 1.4GHz CPU, 1GB RAM and 512M HDD. Unfortunately , the MetaROUTER feature is NOT supported on such high performance hardware. Typically common usage only consume less than 5% performance. I would like to have more flexibles and hereby request to enable MetaRouter on RB4011iGS+RM/5HacQ2HnD . Hopefully it could come soon with the efforts of MikroTik people. Appreciates!
