mgmt/glusterd : volume set validation fixes
This is the new version of the patch by Kaushik at review.gluster.com/699 The following new option types have been introduced: * GF_OPTION_TYPE_INTERNET_ADDRESS_LIST * GF_OPTION_TYPE_PRIORITY_LIST * GF_OPTION_TYPE_SIZE_LIST and option types of several options in translators have been updated to use the new types. valid_internet_address(), valid_ipv4_address() & valid_ipv6_address() functions has been updated for * wildcard matching. Previously used standalone wildcard address checking functions have been removed. Changes have been done to stripe translator to correctly set, update and use stripe-blocksize. Also minimum value for block-size has been set to 16KB.
