-v flag redefined when using with github.com/golang/glog

[AfakTolgi]

"github.com/aristanetworks/goarista/lanz" import in lanz plugin of telegraf defines the -v flag which is being redefined by "github.com/openconfig/ygot/ygot" causing telegraf to crash

Telegraf debug logs ./telegraf flag redefined: v panic: ./telegraf flag redefined: v

You can work around this issue with https://github.com/aristanetworks/glog2glog. To use you would place in your go.mod file:

replace github.com/golang/glog => github.com/aristanetworks/glog2glog v0.0.2

We could also consider removing the glog dependency in the lanz package.

We are actually not using "github.com/golang/glog" module but it is used by the module "github.com/openconfig/ygot/ygot" which we are using.

That's okay. As long as you can modify your program's go.mod file, then you can apply the workaround I described above.

The lanz package no long depends on glog, so this issue should be resolved.
