This PR will implement issue detailed here and described below: #7763
Match Patterns and Templates
Wildcard support based on match patterns and templates.
A match pattern matches an incoming URL path.
Match patterns support glob operators to match URL text and variable definitions to bind matched text to names.
Template patterns are used to re-write URLs.
Template patterns build new URLs and may reference variables bound by a match pattern.
Match Examples
/**.m3u8 would match /foo.m3u8 and /foo/bar.m3u8.
/{dir_name}/*.ts would match /example/file.ts and bind dir_name="example" for a later template match to use.
/{dir_name}/**.ts would match /example/path/file.ts and bind dir_name="example" for a later template match to use. This would also match /example/.ts, which may or may not be a desired behavior.
/{path=v1/*}/{file=*.ts} would match /v1/example/movie.ts (binding path="v1/example" and file="movie"), but would not match /v0/example/movie.ts.
