Update metrics & enable lds cache

[johnlanni]

Ⅰ. Describe what this PR did

1. The previous liteMetrics was already quite comprehensive, so it is used as the default metrics
2. When liteMetrics=true, the behavior is modified to not perform any tag extraction in the data plane
3. LDS cache is enabled by default

Ⅱ. Does this pull request fix one issue?

Ⅲ. Why don't you add test cases (unit test/integration test)?

Ⅳ. Describe how to verify it

Ⅴ. Special notes for reviews
