telemetry: fix tememetry data and update reported fields

[AstroProfundis]

What problem does this PR solve?

• Fix wrong "cluster UUID" used for telemetry reports for clusters, use hashed cluster name instead
• Add "installation UUID" of the tiup instance to identify unique users
• Add "telemetry secret" to use as salt when hashing field values before uploading telemetry info
• Include tiup and tiup-cluster build info in the telemetry report
• Hash more critical field values, hash everything with the "telemetry secret" as salt so that same values used by different users produces different hashes

Check List

Tests

• Unit test

Code changes

• Has exported function/method change
• Has exported variable/fields change
• Has persistent data change

Side effects

• Increased code complexity

Related changes

• Need to cherry-pick to the release branch

It's not a good practice to modify existed field in protobuf.
Make sure it's compatible with old servers/clients.

[AstroProfundis]

We didin't use protobuf at all, it was only used to generate the structs definitions, and the actual data send to telemetry server is using json.Marshal() with those structs.
