failed to parse "system_uptime_format"

[quinten-lp]

Hi, here a issue I have with an update to the last version of telegraf.

Relevant telegraf.conf

here the telegraf configuration file : 


[[outputs.prometheus_client]]
    listen = "0.0.0.0:9126"
[[outputs.http]]
    url = "https://<url>/api/v1/write"
    data_format = "prometheusremotewrite"
    tls_ca = "/etc/monitoring/ca.crt"
    tls_cert = "/etc/monitoring/cert.crt"
    tls_key = "/etc/monitoring/cert.key"
    timeout = "30s"
    [outputs.http.headers]
    Content-Type = "application/x-protobuf"
    Content-Encoding = "snappy"
    X-Prometheus-Remote-Write-Version = "0.1.0"

[[inputs.cpu]]
    percpu = true
[[inputs.disk]]
    ignore_fs = ["tmpfs", "devtmpfs", "devfs", "iso9660", "overlay", "aufs", "squashfs"]
[[inputs.diskio]]
[[inputs.mem]]
[[inputs.system]]
[[inputs.swap]]
[[inputs.netstat]]
[[inputs.nstat]]
[[inputs.kernel]]
[[inputs.processes]]
[[inputs.interrupts]]
[[inputs.linux_sysctl_fs]]

...


### Expected behavior

Running telegraf without errors logs

### Actual behavior

Installation and running telegraf is OK, sending metrics to prometheus is OK but I have a lot à error in my logs like this : 

`[serializers.prometheusremotewrite::http] some series were dropped, 612 series left to send; last recorded error: failed to parse "system_uptime_format": bad sample value " 3:52"`
