Use wwan-automated nested part in SRU test plan (bugfix)

[pieqq]

WARNING: This modifies com.canonical.certification::sru-server

Description

Replacemobilebroadband-cert-automated with wwan-automated nested part, as the wwan-automated test plan includes better coverage for WWAN-related tests.

Add after-suspend-wwan-automated counterpart to make sure there are no issues with WWAN after resuming from suspend.

This is a follow-up to work done by QA in the certification-client desktop test plans (see https://github.com/canonical/checkbox/pull/821)

IMPORTANT: PR #1500 is required before merging this.

Tests

Used checkbox-cli expand com.canonical.certification::sru to generate the list of executed jobs and templates before and after applying this patch. The diff is the following:

$ diff /var/tmp/cer-2738-before.log /var/tmp/cer-2738-after.log 
2a3
> Job 'com.canonical.certification::after-suspend-wwan/detect'
74,75d74
< Job 'com.canonical.certification::mobilebroadband/cdma_connection'
< Job 'com.canonical.certification::mobilebroadband/gsm_connection'
140a140,143
> Template 'com.canonical.certification::wwan/3gpp-scan-manufacturer-model-hw_id-auto'
> Template 'com.canonical.certification::wwan/check-sim-present-manufacturer-model-hw_id-auto'
> Job 'com.canonical.certification::wwan/detect'
> Template 'com.canonical.certification::wwan/gsm-connection-manufacturer-model-hw_id-auto'

showing that:

• a modem detection job is run before and after suspend
• a job to check if a SIM card is present is added
• a job to scan the 3g++ connections available is added
• an automated GSM connection job is still present to replace the one used in the mobilebroadband test plan
