Change status code used for redirects from StatusTemporaryRedirect (3…

HTTP code 307 aka. StatusTemporaryRedirect is used throughout the
project. However, the endpoints redirected to explicitly expects
the client to make a GET request.

If a HTTP client issues a POST request to a server and receives a
HTTP 307 redirect, it forwards the POST request to the new URL.

When using 302 the HTTP client will issue a GET request.

Fixes #287

server: fix reset password test

travis: quote cwd build-docker-push script

TestResetPasswordHandler depended on makeToken begin called twice
during the initialization of a single test case and later assuming
the result would match. Because the token has a timestamp accurate
to the second, occasionally the timestamps would be slightly off
within a single test case and cause the test to fail.

Adding a sleep statement to makeToken would cause the test to fail
reliably.

Define a single token for each test case outside of the struct
initializer so test cases compare the same token.

Closes #274

Additionally remove logging statements that dump entire HTML pages.

*: move user API auth to middleware and fix return status

Closes #272

*: upgrade to go 1.5.3

The "redirectURLs" field in the client metadata has been updated
to the correct "redirect_uris". To allow backwards compatibility
use Postgres' JSON features to update the actual JSON in the text
field.

json_build_object was introduced in Postgres 9.4. So update the
documentations to require at least this version.

Update dex to comply with the changes to fieldnames and types of
the client and provider metadata structs in coreos/go-oidc.
