Currently, autocert.Manager always generates EC-based certificates.
This change adds an optional field forcing the Manager to use RSA
instead.
An alternative idea, a "double" certificate, where the Manager
presents either RSA or EC certificate based on client's compatibility,
doesn't seem to be worth the implementation time given the constant
increase in Elliptic Curve cryptography.

If no key is provided in the *acme.Client, one is generated, but it
is not cached. This means that every restart of the server process
will use a new account.
This change caches the account key, if one is generated, so that
restarts of the server process use the same key.

This change also gets the Manager closer to being able
to cleanup in short-lived HTTP servers running in a long-lived binary.

The package was incorrectly importing both, x/net/context
and the new context packages.
This change makes autocert use only x/net/context to provide
compatibility with the older versions of Go.

A cert renewal loop is started when a certificate is fetched
from cache for the first time or a new one is created.
At most one renew loop is running per domain.

It is quite often the case users need to poll an authorization until it
reaches a final state.
This change adds a handy method to do exactly that,
as well as updating autocert.Manager to use the new method.

This change improves tests speed further by switching to EC keys where
possible.
We are also switching to EC-based token certs for TLS-SNI-x challenges
in this change. I've confirmed it works with Let's Encrypt production
servers as well, by fulfilling TLS-SNI-01 challenge for a test domain
using autocert.Manager.

Sanjay came up with this idea of a more flexible way
to place restrictions on the Manager using a HostPolicy hook
instead of the static DNSNames field.
HostPolicy allows for user-made custom policies,
as well as makes it possible to change the set of host names
dynamically, without restarting the Manager.

This change makes the tests run considerably faster on GOARCH=386
by reducing test RSA keys to 512-bit size.
It also increases GetCertificate test timeout to allow for slower

Package autocert provides automatic access to certificates
from Let's Encrypt and any other ACME-based CA.
It is heavily based on the ideas from rsc.io/letsencrypt.
