Updated mp endpoint

[nivemaham]

This branch consists merges from update_build and read_bin_csv branches. On top of that , i have implemented fixes such as

• Make rest-api -> management-portal requests with valid tokens
• Add client-scopes to client configs
• Efficiently store, load MP related resources in context.
• Use actual instance of MP in integration test and remove wiremock
• Updated integration test to use a valid token
• Uses local MP-SNAPSHOT version with some fixes in OAuth-client-util
• Added project specific resources in separate endpoint class and test-cases in integration test.
• Fixed chekstyle issues
• removed redundant config loading and removed unnecessary config properties and load from a single config file.

Note: I have commented out the e2e test, since i am working on a separate docker-compose file to have a reducedStack. I think it will be easier to review and will give clear separation of changes that are made.

This is PR is rather large, since it contains two not merged branches.

@yatharthranjan @blootsvoets Guys, can we make this a priority and finish reviewing, Please. If this is merged we can have designated branches to do upcoming changes. Since future changes could be large it is good have a separation.
