A new --stdin flag for parsing logs from stdin

A new --stdin flag has been added, allowing parsing logs from stdin. This flag is helpful when applying the same template to local logs.

stern --stdin --template \
  '{{with $msg := .Message | tryParseJSON}}{{toTimestamp $msg.ts "01-02 15:04:05" "Asia/Tokyo"}} {{$msg.msg}}{{"\n"}}{{end}}' \
  <etcd.log

Additionally, this feature helps test your template with arbitrary logs.

stern --stdin --template \
  '{{with $msg := .Message | tryParseJSON}}{{levelColor $msg.level}} {{$msg.msg}}{{"\n"}}{{end}}' <<EOF
{"level":"info","msg":"info message"}
{"level":"error","msg":"error message"}
EOF
