introweb: fix connection hints for server announcements

A long time ago, the introducer's status web page would show the
advertised IP addresses for all published services, by parsing their
FURL's connection hints. This hasn't worked since about 12-Aug-2014 when
foolscap-0.6.5 changed the internal format of these hints (the column
has been empty this whole time).

This removes the "Advertised IPs" column from the Service Announcements
table. Instead, the service's full connection hints (not just the IP
address) is displayed in a tooltip/popup on the "Announced" timestamp
column.

The code that pulls these connection hints is now tolerant of all three
foolscap styles:

* foolscap<=0.6.4 : tuples of ("ipv4",host,port)
* 0.6.5 .. 0.8.0  : tuples of ("tcp",host,port)
* foolscap>=0.9.0 : strings

fixes ticket:2510

remove "announcement_distinct_hosts" from introweb JSON

The machine-parseable JSON output for the introducer status web page
used to include a key named "announcement_distinct_hosts", which counted
the number of distinct IP addresses advertised by all connected storage
servers. This hasn't worked since Aug-2014 when foolscap-0.6.5 change
the internal hints format.

This removes that field.

introducer: stop tracking hints for subscribed clients

A long time ago, the introducer's status web page would show the
advertised IP addresses for all subscribers, by parsing their
RemoteReference's FURL's connection hints. This hasn't worked since
about 12-Aug-2014 when foolscap-0.6.5 changed the internal format of
these hints.

This removes the feature: we no longer attempt to show advertised IP
addresses of subscribed clients. It also removes the code that looked
inside foolscap internals for this information.

travis: use 'git fetch' to deepen, not 'git pull'

Travis builds of branches (i.e. pull-requests) were testing the wrong
thing, because the 'git pull' was causing current trunk to be
auto-merged. At least that's what seemed to break
https://travis-ci.org/tahoe-lafs/tahoe-lafs/jobs/81517826 : it hung
forever waiting for a commit message to be entered.

Also add "sudo: false" to use travis containers (faster) instead of new
VMs. We only use pip to install dependencies, not apt, so we don't need
root.
