How to use a proxy to access ims-na1.adobelogin.com ?

Hi!

I need to use the aio-lib-java-cloudmanager on a host where you would need a proxy to access the cloud manager api at `ims-na1.adobelogin.com` . How can I do this? Unfortunately, setting the system properties -Dhttp.proxyHost=proxy.stw.intra -Dhttp.proxyPort=8080 doesn't seem to do anything there. Is there another way to set a proxy?

Thank you so much, and thanks for this nicely done library!

Best regards,
Hans-Peter

#### Platform and Version

aio-lib-cloudmanager version 1.0.0 running on OpenJDK 1.8.0_265-b01 on Linux

#### Sample Code that illustrates the problem

AdobeClientCredentials credentials = new AdobeClientCredentials(orgId, technicalAccountId, clientIdApiKey, clientSecret, privateKey);
IdentityManagementApi imApi = IdentityManagementApi.create();
String token = imApi.authenticate(credentials);

should *not* work when running it if you set an invalid proxy, -Dhttp.proxyHost=nowhere.neverland -Dhttp.proxyPort=8080 , or whatever way is appropriate to set a proxy. Conversely, if you set a proxy, it should be used. But perhaps there is another, right, way to set a proxy.
