N°1001 setup add check for new MySQL requirement innodb_large_prefix

Browse Source 
if disabled indexes will be limited to 767 bytes, that means 191 car in the new iTop charset utf8mb4 although the varchar iTop use are 255 car long. So we NEED this parameter to be set to true (its default value is true only since MySQL 5.7.7, see https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_large_prefix)
