Draft: MSDKANDRD-1828 Update Gateway URL wrt product flavors.

Changes:

• Modified Gateway URL to match with the new requirement.
• Rename prodEU flavor to stagEU
• Rename none flavor to prod
• local builds(stagXX flavor) utilize gateway URL using the STAGE_GATEWAY_URL parameter in the credentials.properties file.
• Updated pipeline scripts to use stageEU flavor during pipeline execution. To utilize stagging gate way URL for executing jobs like test cases, code coverage in pipeline.
• Prod flavor will always utilize Production gateway URL.
• When build parameter STAGE_GATEWAY_URL is passed at runtime in Development/Feature branch pipeline, it will utilize defined gateway url for execution.
• Feature branch pipeline uses stage flavor in pipeline jobs.

Ticket: https://securetrading.atlassian.net/browse/MSDKANDRD-1828

Requirements:

• Rename prodEU flavor to stagEU
• Rename none flavor to prod
• Configure code base to use Production gateway URL by default
• Introduce new build parameter to be use as Stagging gateway URL (default value empty).
• The Staging gateway URL should be kept internal to the team and not exposed externally.
• In the SDK code, when configuring the gateway, it should check for the build parameter with the Staging gateway URL. If empty, it should default to the Production gateway URL.
• Configure the code base to use the Staging gateway URL in the pipeline for development/feature branches.
• Configure the code base to use the Production gateway URL in the pipeline for the master branch.

Pipeline for Development/Feature Branch:

• Uses Stagging gateway URL.
• Runs test cases, code coverage using debug build type.

Pipeline for master branch:

• Uses Production gateway URL.
• Runs default test cases, code coverage using debug build type.
• Test cards will be used to execute test cases in the master branch against the Production gateway url.
