Increase size of service-parameter field value

This submit increases the size of the “value” field for the
service-parameter table from 255 to 4096 characters. This is
to accommodate registries that can be saved as a list in
this field.

This change was tested in lab with a size of 4096 and 4097
for no_proxy's value.
