Code:
awk 'BEGIN {
  print "name", "fallback_ip", "member", "member" 
  }
/^ *(name|fallback_ip|member)/ {
  data[++i] = $2
  }
/^}/ {
  for (j = 0; ++j <= i;)
    printf "%s", (data[j] (j < i ? OFS : ORS))
  i = 0
  }' infile

If you want to remove the double quotes:

Code:
awk 'BEGIN {
  print "name", "fallback_ip", "member", "member" 
  }
/^ *(name|fallback_ip|member)/ {
  $2 ~ /^"/ && $2 = substr($2, 2, length($2) - 2)
  data[++i] = $2
  }
/^}/ {
  for (j = 0; ++j <= i;)
    printf "%s", (data[j] (j < i ? OFS : ORS))
  i = 0
  }' infile

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
