Cookie scoping path should contain the topology name

When using knox in PROXY only mode, cookies are set with the following domain and path.

*https://sandbox-hdf.hortonworks.com:5443/gateway/local-hdf/ambari#/login*
I login to ambari on this URL, and I get a cookie with
domain: sandbox-hdf.hortonworks.com
path: gateway

If I try to access another ambari instance through the same knox in the following URL:
*https://sandbox-hdf.hortonworks.com:5443/gateway/local-hdf2/ambari#/login*
domain: sandbox-hdf.hortonworks.com
path: gateway

So basically this cookie will overwrite the previous one and will trigger a logout from the first ambari ui.

Proposed solution:
include the topology name in the cookie path:
domain: sandbox-hdf.hortonworks.com
path: gateway/local-hdf
