validation of API input parameters

[Seeni]

We could implements a set of standard validation functions to check the inputs
of valence APIs.

for example, criteria is mandatory for compose, if criteria is absent in the parameter now, an error will raise at PODM side. Rather we could implement parameter validation at API part.

As the flask reqparse is slated for removal, shall we use voluptuous/schema/valideer or to have our own?

Use schema to validate those parameters sounds great to me.
