DG-1697: Adding endpoint for linking/unlink policy

[arpit-at]

Change description

Created two new endpoints in the metastore:

1. Unlink Policies

Endpoint: POST entity/{policy-id}/unlink-business-policy
Body: {"unlinkGuids":["assetId1", "assetId2"]}

2 Link Policies

Endpoint: POST entity/{policy-id}/link-business-policy
Body: {"linkGuids":["assetId1", "assetId2"]}

These endpoints link or unlink policies from a set of asset IDs with minimal operations:

1. Verify if the request is from a service account.
2. Loop through all assets.
3. Load each asset.
4. Link or unlink the policy.
5. Increment or decrement the asset policies count.

do we already have created these attributes on Asset typeDef assetPolicyGUIDs & assetPoliciesCount?
If not then these will never be written to Cassandra & eventually not sync to ES as well

Either add new attributes on Asset OR in case you will run tests on custom tenant you can update typeDefs directly using API & pause typeDef seeder cron

[nikhilbonte21]

I guess this only required for writing assetPoliciesCount.
Instead, just fetch current assetPoliciesCount & add 1 & save it

Don't have the full context here so feel free to ignore this -- the policy-id in url feels like resource id for entity. Would it be more clear to restructure the url to -- entity/business-policy/{policy-id}/link. Unless policy is also an entity.
