#897 imm: Add config attribute to imm class OpensafImm for allowing long DNs

[Anders Bjornerstedt]

The enhancement for supporting long DNs in OpenSAF 4.5 needs to be complemented
by a new added config attribute for controlling if long DNs are allowed or not
on a per site (imm database) basis.

The attribute will be added to the existing class OpensafImm of which there is
only one instance: opensafImm=opensafImm,safApp=safImmService.

This is a schema upgrade, typically followed by a CCB updating the new attribute
to allow long DNs.

Any cluster-start/restart using OpenSAF4.5 will automatically get the attribute
added by special logic in the immsv.

But for sites that upgrade from OpenSAF4.4 or earlier, to OpenSAF4.5
AND that wish to open up support for long DNs, then an explicit schema
upgrade of the class OpenSafImm is also needed before or after the
upgrade step to OpenSAF4.5.

By default, the configuration attribute has a value that does not allow long
DNs. This is to guard against unintentional acceptance of long DNs.
