[TableauOperator] Use params by template_fields

[seunggabi]

I want to use dag params on TableauOperator.
So, I suggest this code.

as-is

task_refresh_workbook_blocking = TableauOperator(
    resource="workbooks",
    method="refresh",
    match_with="id",
    find="MyWorkbook",
    blocking_refresh=True,
    task_id="refresh_tableau_workbook_blocking",
    dag=dag,
)

to-be

task_refresh_workbook_blocking = TableauOperator(
    resource="workbooks",
    method="refresh",
    match_with="{{ params.match_with }}",
    find="{{ params.find }}",
    blocking_refresh=True,
    task_id="refresh_tableau_workbook_blocking",
    dag=dag,
)

Option 1: Quick solution.

overwrite class attribute

from airflow.providers.tableau.operators.tableau import TableauOperator

TableauOperator.template_fields = {"match_with", "find"}

create new operator based on TableauOperator

from airflow.providers.tableau.operators.tableau import TableauOperator

class AwesomeTableauOperator(TableauOperator):
    template_fields = {"match_with", "find"}

Option 2: Long-term Solution

Make other potential users of Tableau Provider happy and make a PR with appropriate changes in TableauOperator.
