Jared Camins-Esakov 297d22459f Bug 6913: More options for koha-create and koha-remove
This commit makes koha-create more flexible by adding a number of command-line
and configuration options.

The biggest change is to add support for pre-determined MySQL credentials using
a file in /etc/koha/passwd (for security reasons, if you use this feature, make
sure the file is not world-readable). The configuration file has the following
format:
instance:user:password:database
The database is optional, but the other two are both required if you want to
specify MySQL credentials. If no credentials are specified for a given instance,
the standard koha_instance username and an auto-generated password are used.

The following additional command line options are now available:
* --use-db - use a pre-existing database, see also --database
* --database - specify the name of the mysql database (still defaults to
  koha_instance)
* --passwdfile - specify a custom (Koha) passwd file for MySQL credentials

The following additional variables are now available (for use in
koha-sites.conf or a custom config file):
* OPACPORT (previously added but not documented) - port on which the OPAC
  should be served
* OPACPREFIX - prefix for the OPAC's virtual host
* OPACSUFFIX - suffix for the OPAC's virtual host

This commit also adds the --keep-mysql option to koha-remove, which, if
specified, will prevent koha-remove from deleting the database or MySQL user
when removing an instance.
