Update hyper-openssl requirement from 0.2 to 0.7 in /vault-api

[dependabot-preview]

Updates the requirements on hyper-openssl to permit the latest version.

Changelog

Sourced from hyper-openssl's changelog.

[v0.7.0] - 2018-11-13

Changed

• Upgraded tokio-openssl to 0.3. Handshake errors now return openssl::ssl::HandshakeError
  rather than openssl::ssl::Error.

[v0.6.2] - 2018-11-07

Added

• Added ALPN support. If the h2 protocol is selected during the handshake via ALPN, the connector
  will automatically indicate that to Hyper via the Connected::negotiated_h2 method. The
  HttpsConnector::new method configures ALPN to support both the h2 and http/1.1 protocols.
  Code using HttpsConnector::with_connector will need to configure ALPN manually.

[v0.6.1] - 2018-06-13

Changed

• MaybeHttpsStream now delegates AsyncRead::read_buf and AsyncWrite::write_buf to support
  readv/writev over HTTP connections.

[v0.6.0] - 2018-06-04

Changed

• Upgraded to hyper 0.12.
• The callback closure now takes a &Destination rather than a &URI to match what Hyper provides
  to connectors.

[v0.5.0] - 2018-02-18

Changed

• The HttpsConnector::with_connector function now takes an SslConnectorBuilder rather than an
  SslConnector due to a change in the session caching implementation. This is requried to
  properly support TLSv1.3.

[v0.4.1] - 2018-01-11

Changed

• Stopped enabling default features for hyper.

[v0.4.0] - 2018-01-11

Removed

• The HttpsConnector::danger_disable_hostname_verification method has been removed. Instead, use
