search_phenotype_association_sets automatically requests pageSize 0

[ahwagner]

The search_phenotype_association_sets method (and presumably other methods that use the ga4gh.client.protocol module) automatically requests a page size of 0. This can lead to bad requests on servers not configured to explicitly handle page size 0 requests (e.g. http://rest.ensembl.org:8080/ga4gh/datasets/search).

I suggest that we change this to a positive integer default, or omit it entirely and leave it to the server to specify the page size.

alternatively, it may be worthwhile to at least allow page size to be passed as a parameter to search_phenotype_association_sets and other search methods.

@bwalsh, have you had to handle this issue in the past?

@ahwagner I did a quick check of the python code, nothing stood out as special case for page_size 0

+1 to changing the default to not 0 https://github.com/ga4gh/ga4gh-server/issues/1362
