Warn about long run time of init. 

Summary:
I, like many before me, had to Google why react-native init appeared to hang the first time I tried it.

It turns out it can just take a really long time, but does not give any warning of this fact.

This patch provides such a warning.
Closes https://github.com/facebook/react-native/pull/9406
