Add --noIndexRestore to mongorestore options

[fancyremarker]

This raises an interesting issue, so please feel free to reject; --noIndexRestore is only supported in mongorestore version 2.2.0 and higher. Adding --noIndexRestore to the arguments of an older version of mongorestore will result in an error.

Perhaps mongoid-shell could add even more value by providing tool version portability for arguments like this? So if :noIndexRestore was included among the options to Mongoid::Shell::Commands::Mongorestore.new, the gem could make a decision about whether to actually include it in the command string, based on the version of the underlying tool?

I think it's totally fine, the job of this gem is to make shell command lines, then the command fails if it fails. Can you please update CHANGELOG too? Thx.

Updated CHANGELOG, and also README.
