Unpin PasteDeploy dependency version

Fixes bug #1133262

There are no newer releases of PasteDeploy than 1.5.0 and we have no
reason to believe newer versions will break us. Indeed, if an
incompatible version is released, we will want to know about it quickly.

Ensure max length of iptables chain name w/o prefix is up to 11 chars.

The maximum length of Linux iptables chain name must be less than or
equal to 28 characters. In iptables_manager binary_name up to 16 chars
is used as a prefix and a '-' follows it, so a chain name passed to
iptables_manager must be less than 12 character long. Accordingky
MAX_CHAIN_LEN should be changed from 28 to 12. Also this commit
introduces a method to get a chain name with valid length.

Since iptables_firewall module constructs a rule by directly using
a chain name, iptable_firewall also must take care of the length.
