MINOR: uri_normalizer: Add a `strip-dot` normalizer

This normalizer removes "/./" segments from the path component.
Usually the dot refers to the current directory which renders those segments redundant.

See GitHub Issue #714.

   The following normalizers are available:
 
+  - path-strip-dot: Removes "/./" segments within the "path" component.
+
+    Example:
+    - /.            -> /
+    - /./bar/       -> /bar/
+    - /a/./a        -> /a/a
+    - /.well-known/ -> /.well-known/ (no change)
+
   - path-strip-dotdot: Normalizes "/../" segments within the "path" component.
       This merges segments that attempt to access the parent directory with
       their preceding segment. Empty segments do not receive special treatment.
