Support for Trigger filters about openwhisk-package-cloudant

[timwis]

Yes please! Otherwise my function will be triggered every time any change happens. I only want to know when new records of a certain category are created.

@csantanapr - this is complete

We should not pass filter name and query parameters in a single string.
The query parameters should be it's own feed action parameter
So the new proposal would be

wsk -v trigger create myTrigger --feed /org_space/cloudantPackage/changes \
 --param dbname mydb --param filter mailbox/by_status --param query_params "{\"status\":\"new\"}"
