Revert the AWS signed fetch work

This isn't working when we pull it into next-article and it hasn't been
released yet. We don't understand this work enough to debug it and get
it working and it's blocking our n-logger work from being merged and
released. We'd like to revert everything.

As it appeared in two different PRs, I decided to revert it commit by
commit. The PRs are:

  - #86
  - #93

The commit hashes I reverted in order are:

  - 826ca12
  - b848fa4
  - 5f6b1f5
  - ffef3f8
  - ce7e591
  - 8af8c24
  - 2c49ac9
  - 0e5ec8f
  - 2ed8545
  - 698302b
  - 6fd9cd5
  - 6fd9cd5
  - 2f229b8
  - 48f79ce

I'll be installing this branch in next-article before merging so that I
can be sure that I didn't miss anything and that it's safe to install
the latest version of n-es-client in our apps.
