Bump okhttp from 3.14.2 to 4.2.2

[dependabot-preview]

Bumps okhttp from 3.14.2 to 4.2.2.

Changelog

Sourced from okhttp's changelog.

Version 4.2.2

2019-10-06

• Fix: When closing a canceled HTTP/2 stream, don't send the END_STREAM flag. This could cause
  the server to incorrectly interpret the stream as having completed normally. This is most useful
  when a request body needs to cancel its own call.

Version 4.2.1

2019-10-02

• Fix: In 4.1.0 we introduced a performance regression that prevented connections from being
  pooled in certain situations. We have good test coverage for connection pooling but we missed
  this because it only occurs if you have proxy configured and you share a connection pool among
  multiple OkHttpClient instances.

  This particularly-subtle bug was caused by us assigning each OkHttpClient instance its own
  NullProxySelector when an explicit proxy is configured. But we don't share connections when
  the proxy selectors are different. Ugh!

Version 4.2.0

2019-09-10

• New: API to decode a certificate and private key to create a HeldCertificate. This accepts a
  string containing both a certificate and PKCS Github API V2 shuts down #8-encoded private key.

  val heldCertificate = HeldCertificate.decode("""
