2a2bab3d28 Add network interface stats 
We do not have to collect these often, so for now set the collection
interval to 120s (even though the Stackdriver exporter is still set to
export every 60s).

Improve systemctl check, style + cleanup

4df720c2a0 Improve systemctl check, style + cleanup 
- Use `systemctl is-active` to check if service is running
  - Cleaner that `grep` on `systemctl status` output
  - Return success means service is running/active
  - Return failure means not running which could be due to
    stopped/failed service or that service does not exist

- Use `command -v` instead of `which`
  Ref: https://github.com/koalaman/shellcheck/wiki/SC2230

- Follow Google "Shell Style Guide": indent, use "readonly"

- Minor: Rephrase comment, avoid all caps

a91b568149 Support "nf_conntrack", check 90% full, style 
- Script was checking for "ip_conntrack_..." which was replaced by "nf_conntrack_..." on newer system. Now support both.

-  Return failure ("not ok") when table is more than 90% full.
  - Not sure what value is best here but I think that is better than when the table is full.
    Otherwise we might end up with a value close to the max or bouncing around.

- Replaced cat by "$(< file )" to avoid calling external command
- Follow Google "Shell Style Guide": 2 space indent, use preferred "[[ test ]]", add "readonly"
- Include current connection usage in output message

f9b5e60a43 Add e2e test for NPD 
The first test is a very simple test. It installs NPD on a VM, and then
verifies that NPD reports metric host_uptime in Prometheus format.

b579984f0a Fix abrt-adaptor config for cpp problems 
This modifies pattern for catching cpp problem messages produced by
ABRT. Found that not all mentioned messages fit into former pattern.
For example following is valid cpp problem message produced by ABRT:

Process xxx (bad_binary) crashed in Will::Fail::a() [clone .isra.2]()

but doesn't fit former pattern, since it's last part contains
whitespaces.
