Allow project name to be specified

[Ryan J Ollos]

Discussed in ​gmessage:trac-users:62Eu-uJZWEw/tapHQ1bKBgAJ, we could add a [project] short_name option that is an alternative to the environment name for referencing a project. When [project] short_name is not set, the value could default to the environment name.

1.0.0dev: Inherit from CommitTicketUpdater to simplify implementation

Reuse options of the [ticket] section rather than renaming
them as [multicommitupdater] options.

1.0.0dev: Provide option for setting name used to reference a project

Previously the [project] name was used. Now there is a
dedicated option [ticket] commit_ticket_update_short_name,
which defaults to the environment name.

Refs #12852.

To summarize, the following change need to be made to use the revised plugin:

• Install from svn/multiprojectcommitticketupdaterplugin/1.0.
• Make sure your [components] section is configured as in MultiProjectCommitTicketUpdaterPlugin#Installation.
• Move the standard CommitTicketUpdater options from the [multicommitupdater] section to [ticket] section. The MultiProjectCommitTicketUpdaterPlugin options are now the same as the ​CommitTicketUpdater options.
• Set [ticket] commit_ticket_update_short_name to the name that you wish to use to reference the environment.

I'll bump the version from 1.0.0dev to 1.0.0 if I get confirmation that the plugin is working well.
