chore(deps): use go 1.16

[six-ddc]

Why do you need to upgrade to v1.16? This change will prevent the project from compiling in lower versions.

• go1.16 is using go modules by default
• maintain build go and runtime go version consistencies.
• as CLI app, you dont need to have lower go version for the build

You can use the embd feature for jq and echart.
