add optional shorthand to full refresh command

[dave-connors-3]

resolves #5878

Description

Adds an optional shorthand for the --full-refresh flag!

dbt build -fr for an incremental model passes:

and acts as expected:

create or replace transient table development.dbt_dconnors.incremental  as
        (

with 

final as (

    select * from development.dbt_dconnors.mock_incrementing_source

    
)

select * from final
        );

Opening as a draft for now, assuming I need some testing here, but didn't find a test that quite looked like the right place at first glance!

Personally, I like -fr ("for real"), though I could also see an argument for -f ("force," a la git push)

I would be happy with just updating one of the existing tests/functional tests that do "--full-refresh" with the new shortcut, such as tests/functional/materializations/test_runtime_materialization.py

Looks good!
