Accelerated Tables for Everyone DELAYED to late April/early May

[ianbuywise]

@jshaffstall you just reminded me we already went over this with a question @rickhurlbatt asked when the beta came out, also we had built some code for “all columns except explicitly specified ones to leave out”
we came up with:

@p.colbert

def q_fetch_none_of(table, column_names_to_exclude):
  table = (
    getattr(app_tables, table)  if isinstance(table, str)
    else  table
  )
  return q.fetch_only(*[
    c['name']
    for c in table.list_columns()
    if c['name'] not in column_names_to_exclude
  ])
