Certbot 0.10.0

[Brad Warren]

Certbot 0.10.0 has been uploaded to PyPI. This is one of the largest
Certbot updates we've ever done including changes such as:

* The ability to customize and automatically complete DNS and HTTP
domain validation challenges with the manual plugin. The flags
`--manual-auth-hook` and `--manual-cleanup-hook` can now be provided
when using the manual plugin to execute commands provided by the user to
perform and clean up challenges provided by the CA. This is best used in
complicated setups where the DNS challenge must be used or Certbot's
existing plugins cannot be used to perform HTTP challenges. For more
information on how this works, see `certbot --help manual`.
* A `--cert-name` flag for specifying the name to use for the
certificate in Certbot's configuration directory. Using this flag in
combination with `-d/--domains`, a user can easily request a new
certificate with different domains and save it with the name provided by
`--cert-name`. Additionally, `--cert-name` can be used to select a
certificate with the `certonly` and `run` subcommands so a full list of
domains in the certificate does not have to be provided.
* The subcommand `certificates` for listing the certificates managed by
Certbot and their properties.
* A `delete` subcommand for removing certificates managed by Certbot
from the configuration directory.
* Support for requesting internationalized domain names (IDNs).
* Removal of the ncurses interface. This change solves problems people
were having on many systems, reduces the number of Certbot dependencies,
and simplifies our code. Certbot's only interface now is the text
interface which was available by providing `-t/--text` to earlier
versions of Certbot.
* Hooks provided to Certbot are now saved to be reused during renewal.
If you run Certbot with `--pre-hook`, `--renew-hook`, or `--post-hook`
flags when obtaining a certificate, the provided commands will
automatically be saved and executed again when renewing the certificate.
A pre-hook and/or post-hook can also be given to the `certbot renew`
command either on the command line or in a [configuration
file](https://certbot.eff.org/docs/using.html#configuration-file) to run
an additional command before/after any certificate is renewed. Hooks
will only be run if a certificate is renewed.
* Recategorized `-h/--help` output to improve documentation and
discoverability.
* Busybox support in certbot-auto.
* Many small bug fixes.
