Hey guys,
First of all, a big thank you for the Java SDK. Definitely a very nice library. Great job!

I noticed that okta-http-httpclient is declaring a direct dependency on org.apache.httpcomponents.client5:httpclient5 since version 1.3.1 (introduced by this change).

Upon examining the code, it becomes evident that the library is not using Apache client version 5 as anticipated, but rather it is still reliant on version 4. It is important to note that these two versions, 4 and 5, are separate libraries with distinct Java package names. Migrating from version 4 to version 5 necessitates more than just updating the version number in the pom file; it also entails modifying the code itself.

In my opinion, there are multiple choices available:

• Revert the changes made and return the dependency to HttpClient 4.
• Adjust the code to effectively use HttpClient 5.
• Develop a separate implementation to provide HttpClient 5 as an additional option alongside OkHttp and HttpClient 4.
