Commit Message

user option: support external command shellouts, closes #101

This commit augments the user option, so that any value wrapped in `backticks`
is treated as an external shell command to execute. The command's STDOUT is
captured for use as the database username for connections, with any leading
or trailing whitespace stripped automatically.

If the command exits unsuccessfully (nonzero exit code) or has no output, it
is treated as an error condition for the directory being processed.

In the backtick-wrapped value, the following placeholder variables are
supported for dynamic interpolation:

  {ENVIRONMENT}: The environment name from the command-line
  {DIRNAME}:     Base name (last path component) of the dir being processed
  {DIRPATH}:     Full path of the dir being processed
  {SCHEMA}:      Schema name being processed, if constant or $ENV
  {HOST}:        Host name
  {PORT}:        Port number of host

These variables are especially useful if you wish to configure a generic
command-line in a top-level .skeema file or global option file, executing a
program/script to determine the appropriate username based on e.g. the
environment (dev vs prod) or the host being connected to.

Previous commit 9a2b471 implements corresponding shellout behavior for the
password option, and between these two commits, feature request #101 is now
fully complete.
