Make percentage string values as floats/ints in InfluxDB (#7879)

Browse Source 
* Make percentage string values as floats in InfluxDB

Currently Z-wave and other compontents report an attributes battery
level as an integer, for example

```yaml
{
"is_awake": false,
"battery_level": 61,
}
```

However, some other components like Vera add the battery level as a
string

```yaml
{
"Vera Device Id": 25,
"device_armed": "False",
"battery_level": "63%",
"device_tripped": "False",
}
```

By removing any % signs in the field, this will send the value to
InfluxDB as an int, which can then be used to plot the data in graphs
correctly, like other percentage fields.

* Add tests and remove all trailing non digits

Adds tests and now removes all trailing non-numeric characters for
better use

* Update variable name for InfluxDB digit checks

Updates the variable used for the regex to remove trailing non digits

* Fix linting errors for InfluxDB component

Fixes a small linting error on the InfluxDB component
