Network request wrapper to avoid duplicating request params and headers

[ccrowley96]

The code below is duplicated in multiple places. @jl-g suggested refactoring the network requests to reduce code duplication.

const axiosData = await axios({
    method: 'get',
    url: this.adtProxyServerURL,
    headers: {
        'Content-Type': 'application/json',
        authorization: 'Bearer ' + token,
        'x-adt-host': this.adtHostUrl,
        'x-adt-endpoint': 'models'
    },
    params: {
        'api-version': '2020-10-31'
    }
});
