Decode and encode with utf-8 before chardet detected encoding

v1.11.4-0.12.4

Try different encoding approach in post_ratelimited

We were getting some SSL bad write retry errors, and mostly the internet
just seems to think that passing in unicode is a bad idea. This tries to
encode the data instead. Try utf-8 first, and if that fails we see if
chardet can get the encoding for us. Also had to encode the
authorization header because it was causing the data body to be coerced
(unsuccessfully) to unicode.

Make Content-Length header value a string

Update post_ratelimited to better handle unicode data

We have this pretty hairy UnicodeDecodeError bug going on:
https://app.clubhouse.io/nylas/story/18092/event-creation-fails-in-syncback-with-unicodedecodeerror

It looks like we have a string with some utf-8 characters in it, but the
string isn't specified as unicode.

My first attempt to fix this was just to call `.decode('utf-8')` on the
data before we passed it down into requests, but that came back to us
with a schema validation error from the provider.

After lots of digging, turns out the Content-Length header was incorrect
:face-palm: Requests doesn't have good enough unicode support to realize
it should calculate the byte length instead of the number of characters.
So, I've rejiggered our request building so that we can calculate the
content length ourselves.
