Add encode to support non-English text data

[muziyoshiz]

When I call awscurl 0.17 with non-English text data, it fails with the following UnicodeEncodeError.

$ awscurl -XGET --service es "${ENDPOINT}/${INDEX}/_search" -d '日本語'

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 126-127: Body ('日本語') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

It is because the data passed to requests.request method is not encoded.
Please check this pull request. Thanks.

@okigan
Thanks for your review!
I added the integration tests both for English data and non-English data. Please check.

Thank you!

@okigan
Would you please let me know when the next release will be?
Now I am using awscurl v0.17 with my patch. It is good to install the latest master version with pip for non-English users like me. Thanks.

next day or two, thanks!

"next day or two" did not account for the thanksgiving week -- hope everyone had a good break as v0.18 is now released and up on pypi, happy awscurling!

[muziyoshiz]

I see 😅 No problem. Thank you very much!
