Handle declared type

[khanhtc1202]

What this PR does / why we need it:

Previously, for queries of kind

{
	Field:    "Kind",
	Operator: datastore.OperatorEqual,
	Value:    model.ApplicationKind_KUBERNETES,
}

the filter logic of filedb will return false even the model object has field Kind of the same value. That is caused by the unmarshaled model object only contains primitive types (to keep filedb layer generic, we only cast raw byte of models to map[string]interface{}, not it true type), and the operand value from queries is of its wrapped type (for instance model.ApplicationKind). As the result, comparing those two values will return (mismatched type model.ApplicationKind and float64) error. This PR provides logic to convert types which not a primitive type of filter.Value to primitive types, so the filter compare logic could work.

Which issue(s) this PR fixes:

Fixes #3494
