Creates secondary name(s) for group names. Once an alias is created the
group name cannot be used to request HTTP playback of that stream. Once
an alias is used (requested by a client) the alias is removed. Aliases
are designed to be used to protect/hide your source streams.

:param groupName: The original group name
:type groupName: str

:param aliasName: The alias alternative to the group name
:type aliasName: str
