Docker swagger definition v1.37 incorrect description of field Data in Create config mode

[dasm0012]

Description

Docker swagger definition v1.37 specifies to use Base64-url-safe-encoded (RFC 4648) config data for the 'Data'-field of the input model for entry POST /configs/create.

However doing so will result in an error; {"message":"illegal base64 data at input byte XXXXX"}

Workaround; Use the standard base64 table1 (as defined in rfc4648#section-4)

Steps to reproduce the issue:

Data before base-64 encoding
<slave_config><max_log_lines>10000</max_log_lines><max_log_timeout_minutes>600</max_log_timeout_minutes><object_timeout_minutes>60</object_timeout_minutes>PDISESSIONIDcf18e2f3531348f7aa6da4a81df172730.0.0.08080TODO-CHANGETOUTILTODO-CHANGETOUTIL</slave_config>

Describe the results you expected:

Either documentation specifies one should use standard base64 table1 (as defined in rfc4648#section-4)
Or have docker API server accept Base64-url-safe-encoded (RFC 4648) as the contents of the 'Data'-field of the input model for entry POST /configs/create
