Okta Configuration: UseProxy was not taken for api configurations

[SoledadIce]

Hi @bryanapellanes-okta,

I just ran into the same issue today. The issue persists in 8.0.1 after the PR #722
And I daggered into the code for a while, the root cause is that the newly introduced UseProxy config hasn't been added to the extension method MergeConfigurations. So, the config is not properly set for most of the Apis.

Could you please kindly make a hotfix? Thanks!

@SoledadIce Please review PR #741; can you confirm that the change there corrects the problem?
