(bigquery) add configuration "column_name_character_map" to dataset load_job

[juseveno]

following the merge of a new configuration option in BQ LoadJob, it would be convenient to add the ability to exploit this new configuration in dataset load_job method

cf. #26252

You can set it in the block passed to load_job:

my_load_job = dataset.load_job "my_new_table", my_file do |schema|
  schema.column_name_character_map = "strict"
end

Adding another argument to load_job makes an already too-long argument list even longer. Is there a reason we need that?

You're right, passing the configuration to the block actually works.
To my opinion, it's better to have all options available directly through the named params of the method, and have not different behaviors depending on the options but it's totally personal.
