[FEAT] Disable InfluxDB certificate verification

[SaswatPadhi]

Is your feature request related to a problem? Please describe.

I use a self-signed certificate on my InfluxDB server. When trying to use this server with scrutiny, it fails to start with an error about unknown certificate authority. This is expected, since the certificate is self signed.

Describe the solution you'd like

Most applications allow disabling SSL verification (e.g., verify_ssl: false in Home Assistant's influxdb integration). It would be nice to have something like that in scrutiny.

Hey @SaswatPadhi
Scrutiny uses the official influxdata/influxdb-client-go sdk under the hood to communicate with the InfluxDB API.

https://github.com/AnalogJ/scrutiny/blob/master/webapp/backend/pkg/database/scrutiny_repository.go#L98

Looks like its possible to customize the TLS config via an option in the Client constructor.

https://github.com/influxdata/influxdb-client-go#options

 client := influxdb2.NewClientWithOptions("http://localhost:8086/", "my-token",
    influxdb2.DefaultOptions().
        SetUseGZip(true).
        SetTLSConfig(&tls.Config{
            InsecureSkipVerify: true,
        }))

Would you be willing to test it out and open a PR?

[SaswatPadhi]

Thanks for the pointer, @AnalogJ!

I'd be happy to test the change and open a PR shortly.

Hi @AnalogJ,

I have tested the changes at my end and just opened a PR for merging it.

Besides the influxdb2 client, there was an http client in InfluxSetupComplete which also required the TLS config tweak.
