If this function gets passed only a `tzinfo` object and no concrete
`datetime`, the returned display name is indenpendent of daylight savings
time. This can be used for example for selecting timezones, or to set the
time of events that recur across DST changes:
>>> tz = timezone('America/Los_Angeles')
>>> get_timezone_name(tz, locale='en_US')
u'Pacific Time'
>>> get_timezone_name(tz, 'short', locale='en_US')
u'PT'
If no localized display name for the timezone is available, and the timezone
is associated with a country that uses only a single timezone, the name of
that country is returned, formatted according to the locale:
>>> tz = timezone('Europe/Berlin')
>>> get_timezone_name(tz, locale='de_DE')
u'Deutschland'
>>> get_timezone_name(tz, locale='pt_BR')
u'Hor\xe1rio Alemanha'
On the other hand, if the country uses multiple timezones, the city is also
included in the representation:
>>> tz = timezone('America/St_Johns')
>>> get_timezone_name(tz, locale='de_DE')

The `uncommon` parameter can be set to `True` to enable the use of timezone
representations that are not commonly used by the requested locale. For
example, while in frensh the central europian timezone is usually
abbreviated as "HEC", in Canadian French, this abbreviation is not in
common use, so a generic name would be chosen by default:
>>> tz = timezone('Europe/Paris')
>>> get_timezone_name(tz, 'short', locale='fr_CA')
