* Adding tests to show config.url mutation

Because config.url is modified while processing the request
when the baseURL is set,
it is impossible to perform a retry with the provided config object.

Ref #1628

* Fixing url combining without modifying config.url

As config.url is not modified anymore during the request processing.
The request can safely be retried after it failed with the provided
config.

This commit fix building url with hash map (fragment identifier) when parameters are present: they must not be added after `#`, because client cut everything after `#`

Resolves #1158

This modifies http.js to uppercase the HTTP method, similar to xhr.js, before passing the request off to the transport. This causes follow-redirects to preserve the HTTP method when automatically making a request to the next URL.

Clarify in README that default timeout is 0 (no timeout)

* Add `getUri` signature to TypeScript definition.

This is in support of #1624.

* Make configuration optional.

- Remove code coverage from SauceLabs CI, as it causes tests to hang.
- Update Safari browser tests to handle Safari 9-11 with proper OS
settings

* Added getUri method

* Removed usage of "url"

* added method to README

* Adding support for no_proxy env variable

* Adds support for the no_proxy environment variable commonly available
  with programs supporting the http_proxy/https_proxy environment
  variables.
* Adds tests to test the no_proxy environment variable.

* Adding documentation for the proxy env variables

* Adds documentation to README.md for the supported, conventional
  http_proxy, https_proxy, and no_proxy environment variables.

the one used in defaults.js
