#2304 add max_line_size, max_headers and max_field_size arguments to ClientSession

[starflows]

What do these changes do?

Allow the user to set the response header limits. The properties max_line_size, max_headers and max_field_size can be set on ClientSession creation. Default values are: max_line_size=8190 max_headers=32768 and max_field_size=8190.
Thus the user can set and - when needed - receive bigger response headers.

Are there changes in behavior for the user?

no, default values are unchanged.
