Server selection
API requires that caller pass in nhosts and an array of IPV4 addresses. Thus, the server selection policy is independent of the gexec system. The parsing of a string a list of tokens (and total count of #tokens) is what token_array will do. We will use this on the GEXEC_SVRS environment variable to get back a list of hostnames/IP addresses. Then, we will run net_hosttoip on each to get 16 byte IPV4 address as a char * so we can pass it to gexec_spawn.
