Subject: [PATCH 13/62] Amended oAuth strategy to resolve m/f/a tuples (#60)

* Amended oAuth strategy to resolve m/f/a tuples

- this allows specifying {m, f, a} tuples for things such as Client ID / Client Secret

* Moved config resolution to after all values have been merged

* Amended Strategy to also derive crednetials from options

- This is in addition to deriving from the Environment

Subject: [PATCH 28/62] Allow newest oauth2 client with security fixes

oauth2 has a recent possibly backwards incompatible release that
makes sure the spec is followed and authorization headers are
respected (https://github.com/scrogson/oauth2/blob/master/CHANGELOG.md#v200-2019-07-15)
This fixed scrogson/oauth2#128 hence I think it's important to
include.
Decided to not require 2.x as that might conflict too hard
with other libraries. Also decided to allow minor version bumps
as @scrogson seems to be good about semver <3
As #66 isn't merged yet I'd like it if this could get in with the
release.

fixes #67

+In some cases, it may be necessary to update the user info endpoint, such as when deploying to countries that block access to the default endpoint.
+
+```elixir
+config :ueberauth, Ueberauth,
+  providers: [
+    google: {Ueberauth.Strategy.Google, [userinfo_endpoint: "https://www.googleapis.cn/oauth2/v3/userinfo"]}
+  ]
+```
+
+This may also be set via runtime configuration by passing a 2 or 3 argument tuple. To use this feature, the first argument must be the atom `:system`, and the second argument must represent the environment variable containing the endpoint url. 
+A third argument may be passed representing a default value if the environment variable is not found, otherwise the library default will be used. 
+
+```elixir
+config :ueberauth, Ueberauth,
+  providers: [
+    google: {Ueberauth.Strategy.Google, [
+      userinfo_endpoint: {:system, "GOOGLE_USERINFO_ENDPOINT", "https://www.googleapis.cn/oauth2/v3/userinfo"}
+    ]}
+  ]
+```
+
 To guard against client-side request modification, it's important to still check the domain in `info.urls[:website]` within the `Ueberauth.Auth` struct if you want to limit sign-in to a specific domain.

Subject: [PATCH 55/62] Remove :applications instructions from readme

Elixir 1.4 (released in 2016) add application inference, so now in
almost all situations it is not necessary to add a dependency to
`:applications`. And if you set just a single application in
`:applications` then you will break your release.

Since ueberauth_google only support Elixir 1.8 and up, we don't need to
mention :applications anymore
