[cli] broken project/tenant arguments handling

[Jacek Tomasiak]

OS_PROJECT_ID/OS_TENANT_ID and OS_PROJECT_NAME/OS_TENANT_NAME are supposed to be used interchangeably.
Current implementation doesn't handle this properly.

Example:
MURANO_URL=http://localhost:8082/ OS_AUTH_URL=http://localhost:5000/v2.0 OS_PROJECT_NAME=demo OS_USERNAME=demo OS_PASSWORD=<password> python shell.py package-list

Results in:
You must provide a tenant name or tenant id via --os-tenant-name, --os-tenant-id, env[OS_TENANT_NAME] or env[OS_TENANT_ID] OR a project name or project id via --os-project-name, --os-project-id, env[OS_PROJECT_ID] or env[OS_PROJECT_NAME]

It works correctly if both OS_PROJECT_NAME and OS_TENANT_NAME (or only OS_TENANT_NAME) are provided.

    Fix checks for Project/Tenant command line arguments

    OS_PROJECT_ID/OS_TENANT_ID and OS_PROJECT_NAME/OS_TENANT_NAME are
    supposed to be used interchangeably. Current implementation doesn't
    handle this properly. It requires "tenant" parameters to be present
    even if "project" arguments are provided. The check is done twice
    which is redundant, inconsistent and catches some paths which don't
    require those arguments at all.

    The redundant check has been removed and better of two available
    checks has been moved to proper place in the code.
