Always load certificates from the same jar as the code

[walkerburgin]

Before this PR

We occasionally hit errors like this while initializing clients in threads with context class loaders:

Caused by: java.lang.IllegalArgumentException: resource ca-certificates.crt not found.
        at com.google.common.base.Preconditions.checkArgument(Preconditions.java:218)
        at com.google.common.io.Resources.getResource(Resources.java:196)
        at com.palantir.conjure.java.config.ssl.DefaultCas.getTrustedCertificates(DefaultCas.java:57)

After this PR

Always load the certificates from the same jar as the code.

Possible downsides?

None that I'm aware of.

What do the change types mean?

• feature: A new feature of the service.
• improvement: An incremental improvement in the functionality or operation of the service.
• fix: Remedies the incorrect behaviour of a component of the service in a backwards-compatible way.
• break: Has the potential to break consumers of this service's API, inclusive of both Palantir services
  and external consumers of the service's API (e.g. customer-written software or integrations).
• deprecation: Advertises the intention to remove service functionality without any change to the
  operation of the service itself.
• manualTask: Requires the possibility of manual intervention (running a script, eyeballing configuration,
  performing database surgery, ...) at the time of upgrade for it to succeed.
• migration: A fully automatic upgrade migration task with no engineer input required.

Note: only one type should be chosen.

How are new versions calculated?

• ❗The break and manual task changelog types will result in a major release!
• 🐛 The fix changelog type will result in a minor release in most cases, and a patch release version for patch branches. This behaviour is configurable in autorelease.
• ✨ All others will result in a minor version release.
