[astute] Prevent endless connection attempts to mcollective

[Vladimir Sharshov]

Prevent endless connection attempts to mcollective in Astute. Instead of it just raise error after several attempts. This behavior provide more user friendly behavior.

Before:

   Retrying RPC client instantiation after exception <ex>
   Retrying RPC client instantiation after exception <ex>
   Retrying RPC client instantiation after exception <ex>
   ....
   Retrying RPC client instantiation after exception <ex>
   <end only if manually kill process>

Now:

   Retrying RPC client instantiation after exception <ex>
   Retrying RPC client instantiation after exception <ex>
   Retrying RPC client instantiation after exception <ex>
   <exception>
