Missing or incorrect information in monitoring responses

[jennifer-richards]

• show peers
  • the "connected_to" and "connected_from" fields always show false, even when a peer is connected
  • the last connection attempt field is blank, even when attempts have been made
• APCs not listed for remote realms
• the expiration time for remote communities is shown as an absolute time, but it is the monotonic clock (which measures time since last reboot).
  • could either fix the display to be relative to now, or could use realtime clock for TRP purposes

The expiration time issue is addressed by 536646258cdf77d28015493c460022e6a239b4f3

Not currently seeing the connected to/from or last_connection issues. However, the TR clearly does not seem to be noticing when a peer disconnects.

[jennifer-richards]

I think all but the APCs for remote realms not being shown has been resolved.

[jennifer-richards]

The system currently copies the "apcs" list for a community update into the "apcs" list for a realm that is created as a result of the update. However, if the community itself was an APC, that list is empty. If the incoming community is an APC, any realms created by the update should be created with that community as its APC.

The last bit should be fixed by #74.

Test

Steps

1. Set up a pair of trust routers as peers. Start them and let them establish their connections.
2. Use trmon [...] show realms and verify that an APC is defined for every realm
3. Use trmon [...] show communities and verify that the expiration times for remote realms appear as future UTC times
4. Use trmon [...] show routes and verify that the expiration times for remote routes appear as future UTC times
5. Use trmon [...] show peers and verify that each peer's connected_to, connected_from, and last_connection_attempt fields are accurate and that the latter is shown in a past UTC time

Expected results

As described in the steps above
