14969831e9 Apply the same style of fix as #87913 but for HTTP methods too. 
Go does not validate HTTP methods beyond len!=0 and that they don't contain HTTP meta chars like a newline. Also to using string sets instead of maps.

cada0270fe Fix nil pointer dereference in metrics value calculator. 
The metrics structure passed to volume stat calculator
can contain real stats on subset of metrics fields. For example,
the metrics structure filled by a CSI driver can have
either INODES or BYTES filled, IOW it a valid return.
In such cases the volume stat calculator panic with below
trace:
