"""Creates a new UpdateManager.
Args:
sdk_root: str, The path to the root directory of the Cloud SDK is
installation. If None, the updater will search for the install
directory based on the current directory.
url: str, The URL to get the latest component snapshot from. If None,
the default will be used.
platform_filter: platforms.Platform, A platform that components must match
in order to be considered for any operations. If None, only components
without OS or architecture filters will match.
warn: bool, True to warn about overridden configuration like an alternate
snapshot file, fixed SDK version, or additional repo. Should be set
to False when using this class for background operations like checking
for updates so the user only sees the warnings when they are actually
dealing directly with the component manager.
Raises:
local_state.InvalidSDKRootError: If the Cloud SDK root cannot be found.
MissingUpdateURLError: If we don't know what manifest to download.
