Use more intuitive labeling for Data Size in Integer in DB options

[seancolsen]

Current behavior

• Configuring a number column requires the user to understand the difference between 2-byte, 4-byte, and 8-byte numbers. Many non-technical users will be confused by this choice.
• The list is not ordered

Desired behavior

• The field label is "Maximum Value"

• The options are as follows (and in the following order)

  • "32,767"
  • "2,147,483,647"
  • "9,223,372,036,854,775,807"

  (These values are taken from the Postgres docs on Numeric Types).

• The grouping separators are applied to the options according to the browser locale.
