[#203] Replace ErrEACLNotFound to core library

Browse source 
ErrEACLNotFound error was defined in implementation package. EACL validator
checked this error after the call of eACL storage interface method. Replace
ErrEACLNotFound to core container library. in order to: on the one hand not
use an implementation error, on the other hand, to be able to reuse a
generic type error (404).
