support filter urls for patientIds and manage limit

[inodb]

The Study View Page has a way to construct filterJSON URL with sample IDs:

https://cbioportal.org/study/summary?id=msk_impact_2017#filterJson={"sampleIdentifiers":[{"studyId":"msk_impact_2017","sampleId":"P-0000004-T01-IM3"}]}

Can we enable the same for using patientIdentifiers and patientId? So something like:

https://cbioportal.org/study/summary?id=msk_impact_2017#filterJson={"patientIdentifiers":[{"studyId":"msk_impact_2017","patientId":"P-0000004"}]}

There is also a URL parameter limit for this filterJSON that we might run into at some point. Wondering if providing POST as another way of supplying the filter would be good in cases where the filterJSON doesn't cut it

Note to self: please let Shai Ahmed from dataline team know once this is implemented
