db_create_table() and db_insert_into()

[krlmlr]

What's the reason for deprecating these functions in ?backend_dbplyr? DBI now has dbCreateTable() and dbAppendTable(). Would it make sense to make db_write_table() a non-generic, or remove all or most specializations of this method in favor of a default method that calls db_create_table() and db_insert_into()?

Last relevant change: 97c22c3.

All the database stuff is gradually getting deprecated in dplyr and being moved either to dbplyr methods or directly to DBI methods.

Plan for this process is recorded in https://dbplyr.tidyverse.org/dev/articles/backend-2.html and the next step in tidyverse/dbplyr#507
