HI,
I have noticed following two typos in the REST API call for ep-policies and virtual-networks in blueprint.py file:

`subratam-mbp:aos subratam$ pwd
/Users/subratam/Library/Python/3.8/lib/python/site-packages/aos
subratam-mbp:aos subratam$ diff blueprint.py.bak blueprint.py
1250c1250
< r_path = f"/api/blueprints/{bp_id}/policies/{ct_id}"

    r_path = f"/api/blueprints/{bp_id}/endpoint-policies/{ct_id}"

2173c2173
< self.rest.delete(f"/api/blueprints/{bp_id}/virtual_networks/{vn_id}")

    self.rest.delete(f"/api/blueprints/{bp_id}/virtual-networks/{vn_id}")
