Subject: dhcp-client: T5760: add constraints for dhclient string options

The string data type specifies either an NVT ASCII string enclosed in double
quotes, or a series of octets specified in hexadecimal, separated by colons.

For example:

set interfaces ethernet eth0 dhcp-options client-id CLIENT-FOO
or
set interfaces ethernet eth0 dhcp-options client-id 43:4c:49:45:54:2d:46:4f:4f

As of now there was no input validation performed.
