public RepeatedField<ExtensionChain.Types.Extension> Extensions { get; }
Required. A set of extensions to execute for the matching request.
At least one extension is required.
Up to 3 extensions can be defined for each extension chain
for LbTrafficExtension resource.
LbRouteExtension and LbEdgeExtension chains are limited to 1 extension
per extension chain.
Required. The name for this extension chain.
The name is logged as part of the HTTP request logs.
The name must conform with RFC-1034, is restricted to lower-cased letters,
numbers and hyphens, and can have a maximum length of 63 characters.
Additionally, the first character must be a letter and the last a letter or
