[Enhancement] Need to verify project id in DB query

[xieus]

Bug Description

Currently when query resource by project id, VPC/Subnet/Route mgr don't check project id which may cause exposing resources of other projects.

Proposed change
This issue should be handled in Alcor common library to offer a generic solution to upstream microservices.

[Gzure]

This issue has fixed in RBAC PR. Are there some problems with the current test?

@Gzure The Rbac PR did resolve part of the problem, where the project id is "translated" from the security token.

The remaining problem here is that when we call an internal service (like VPC mgr) and pass a random project id on the URL, all VPCs show up...

Repro steps:
. Create VPC1 in Project1 (id: 3dda2801-d675-4688-a63f-dcda8d327f50)
. Create VPC2 in Project2 (id: 3dda2801-d675-4688-a63f-dcda8d327f51)
. Curl http://127.0.0.1:9001/project/3dda2801-d675-4688-a63f-dcda8d327f50/vpcs returns both VPCs.
