Remove type from Job Dependencies

[sravankorumilli]

while specifying the dependency user should just provide job_name if with in the same project & if it is depending on other projects user can specify project_name/job_name as the dependency. type: inter/intra is no longer needed for user to specify that detail it should be inferred based on user input.

Even in the code when resolving dependencies we should resolve the dependencies with the key(project_name/job_name) currently we are doing it differently for inter/intra dependencies which will lead into issues when a job depends on two jobs with same name and that exists in different projects.
