Datastore upload dag failing when field name have extra white space on the schema.

[sagargg-zz]

api_ckan_load_multiple_nodes dag failed when the schema fieldname has extra white space at end of name.

Steps to reproduce:

1. Setup ckan instance with ckanext-blob-storage, ckanext-aircan extensions.
2. Upload CSV file with extra space on the column header. eg. 'Field_Name '
3. check the airflow task create_datastore_table_task log, you will see the validation errors even tasks marked as successful.

Possible fix

check and remove whitespace from the schema field name on datapub while creating/generating a schema information
