Ability to use basic authentication using weblog

[di-hardt]

New feature

Give users the ability to provide basic authentication credentials via the weblog URL. So logs can be posted to a secured server.

Usage scenario

Collecting weblogs on remote server which requires a basic authentication. Nextflow call should look like: nextflow run -with-weblog https://user:[email protected] .... main.nf

Suggest implementation

modules/nextflow/src/main/groovy/nextflow/util/SimpleHttpClient.groovy already supports basic authentication, but there is no functionality to extract the credentials from the URL or provide it by a separate parameter.

I implemented it in a fork: https://github.com/di-hardt/nextflow/commit/3ef40cc139c81e535ac18b0ab7a6099c61af2591

If no credentials were provided in the URL or a basicToken attribute is already set the code will simply do nothing.
