Contains Ignorecase Check for ProfileCredentials property keys read from ~/.aws/credentials file.

[lovababu]

Motivation and Context

There is no guarantee that every developer machine having profile configured with lower case property keys.
For example in our case, we are using some python reusable script to setup ~/.aws/credentials file, it actually creates file as below

[default]
AWS_ACCESS_KEY_ID=   
AWS_SECRET_ACCESS_KEY=   
AWS_SESSION_TOKEN=

Due property keys are in upper case, ProfileCredentialsUtil.java @line 143 and 147 is failing due to case sensitive check with containsKey of properties map object.

Modifications

Storing profile credential data as TreeMap with String.CASE_INSENSITIVE_ORDER, it actually doesn't alter any property key-values, but while checking contains key, it considers case insensitivity.

Changes to file: software.amazon.awssdk.profiles.Profile.java#BuilderImpl.java @line 194.

Testing

Maven build passed locally.
Validated through sample java application with updated SDK changes.
Added UT to validate actual change.

Which SDK do you use that works only with uppercase properties?

[debora-ito]

@lovababu we did some research and found out that most AWS SDKs don't support uppercase properties.

Because of this, we won't be able to merge the PR in the Java SDK v2. If this gets implemented, we need to support it consistently across all the SDKs.

We still want to know if more people are interested in this feature, so I created a feature request in our AWS cross-SDK github repo here: #5689. Feel free to add a 👍 to show you are interested.
