The README.md currently reads:

Install Go >=1.13 (1.15 recommended)

However, building with go 1.13 fails.

System info:

CentOS 7 with Go version 1.13

Steps to reproduce:

1. git clone https://github.com/influxdata/telegraf.git
2. git checkout release-1.17
3. make telegraf

Expected behavior:

A successful build of the telegraf build.

Actual behavior:

Build fails with:

build github.com/influxdata/telegraf/cmd/telegraf: cannot load hash/maphash: cannot find module
providing package hash/maphash

Additional info:

From the Golang changelog I gather that hash/maphash which is used e.g. in metric/series_grouper.go appeared in Go 1.14: https://golang.org/doc/go1.14

Thus, it seems necessary to increase the minimum version requirement in README.md from 1.13 to 1.14.
