build: don't instantiate const objects with no user-defined constructor

It seems that some compilers disallow instantiating const objects that
don't provide a user-provided constructor. This would surface as the
following error.

error: default initialization of an object of const type 'const ClusterInfo' 
requires a user-provided default constructor

Yep, that looked suspicious since at line 304 there is similar construct and it 
worked.  Thank you for looking at it again.

I'm curious whether the following (more idiomatic) would help here:

const Cluster info = {};
