Use full URL instead of relative path

• Issue Reference: #68
• Added configuration api.server.fullUrl.enabled to enable full server url in OpenAPI swagger
• Currently only in Azure it is enabled. For Other [CSP/Common Core] there is no change.
• Added the property server.servlet.contextPath to the test properties otherwise it fails when initializing the server for springboot unit tests.

Configuration Details

• api.server.fullUrl.enabled=true It will generate full server url in the OpenAPI swagger
• api.server.fullUrl.enabled=false It will generate only the contextPath
