initialise prevents using a different host than localhost

[jasonmotylinski]

Hi - I'm trying to use the library against an Elasticsearch cluster hosted in AWS. I need to use a different hostname and it appears that initialise prevents me from setting the host value:

Is this the intent? If not, I can submit a pull request.

Oh! You're correct, it's definitely not right. You're welcome to submit a PR for this :)
