W3C distributed tracing-compatible operation id

See original GitHub issue

Currently, ApplicationInsights SDKs support Request-Id header for correlation that looks like |<root-id>.

W3C distributed tracing protocol is going to replace current Request-Id format and is being implemented in ApplicationInsights SDKs.

The first phase of implementing it is a change of the rootId format.

Currently it’s 5 base64 chars, but to enable compatibility with W3C standard, it should be 32 chars [a-z][0-9], lowercase. All zeros is considered invalid. Example of the valid id: 0af7651916cd43dd8448eb211c80319c.

It could be implemented as a lowercase guid without dashes or 16 random bytes encoded into hex string.

The rest: header names and hierarchy in Request-Id could still be preserved (i.e. |0af7651916cd43dd8448eb211c80319c. is a valid Request-Id).
