es-daily-index-maintenance.pl should also delete closed indexes about es-utils

[abraxxa]

This piece of code does what I want on ES 0.90.2:

my $d_res = $es->cluster_state(
filter_nodes => 1,
filter_metadata => 1,
filter_routing_table => 1,
);
my $indices = $d_res->{blocks}->{indices};

Thanks for the code, had to tweak it a bit because not all version provide $d_res->{{blocks}{indices}. This is fixed in 1.003.
