query all direct-connected peers for all seed nodes in watchdog

[ghost-not-in-the-shell]

This PR changes how we query peers in watchdog and make_report.py.

The intention is that we would query all the seed nodes for all their directly connected peers. See #8638 for more details.

This PR also add some more error reporting for the make_report.py.

This PR also fixed the following kinds of errors of the watchdog process:

1. various errors like

  File "/code/metrics.py", line 60, in pods_with_no_new_logs
    mina_containers = list(filter(lambda c: c.name in [ 'coda', 'seed', 'coordinator' ], containers))
TypeError: 'NoneType' object is not iterable

fixed by checking the status of the pods before doing anything

2. handle errors from daemon

  File "<unknown>", line 1
    Error: Unable to connect to Mina daemon.

3. reference to undefined variables

lgtm, though we should probably get a second pair of eyes on this as I am not too familiar with the watchdog script.

This looks effectively fine, if we're cool with in the short term seeds only querying their direct peers (better than what we do right now anyway, it would seem). I have some follow up questions on the long term strategy, but I'll follow up with those elsewhere

LGTM. Could you update the version number in version.txt and do a make release to upload the new image? I'm waiting for a review on #8664 (which updates the version) but you can go ahead and update it to 0.4.8 and I'll change it in my PR
