  1. sql: remove vectorize=201auto option

    `201auto` option of `vectorize` setting has been removed since it no
    longer makes sense to keep (it was introduced as an escape hatch for
    20.2 release). Note that we don't need to bump the distsql version
    because of this change since it is backwards compatible - if the gateway
    is running the old version that has `vectorize=201auto` set, then we
    will check whether flows for all nodes don't have non-streaming
    operators and possibly use `off` option on the flow setup request, then
    the newer version remote node will check the vectorize setting on the
    request whether it is not `off` and setup the vectorized flow if it is
    not.
    
    Release note (sql change): `201auto` value for `vectorize` session
    variable and the corresponding cluster setting has been removed.
