This fixes a variety of bugs where API requests would read uninitialized state, causing crashes or race conditions.

Long story short: Once we create a server and start it, we can't start
it again. We can't close it and restart it, and we can't just start
it without closing it.
Unfortunately, if the server's config needs to change, we have a Problem
here.
This ultimately means that the retry logic for GetListeners can't actually
retry successfully; if we fail on the first attempt, we necessarily fail
on any later attempts also, and if we try to fix that, we get panics.
But!
We don't actually NEED to retry. We just need to ensure that we can
open a :0 port, extract the actual port number, and use that in places
where the port number mattered, without having to rebind it.
The only actual place we needed to rebind things was opening gRPC
servers, so we introduce a gRPC Listener that can be used instead of
trying to bind to a specified port.
In a bunch of other cases where we had similar logic to try to allocate
and then use a port, we can switch to just using a provided listener.
For instance, net/http has `Serve(net.Listener, handler)`, not just
ListenAndServe(addr, handler).
This should eliminate the weird CI failures from eaddrinuse.
NOT fixed: server/cluster_test.go/TestClusterResize_AddNode isn't working
right now. The new node isn't actually being added to the existing cluster.
I attempted this but was outsmarted by it, and I think fixing the
rest of this is worth it as a separate thing.
change logic in version.go so that the trial related messages only appear on trial versions of molecula
convert Command methods in trial.go to functions and pass a loggerLogger variable instead since that was the only piece of Command being used
add a function named expireAfter which seperately runs similar functionality to what was previously in daily check with chnages directed at stopping users from changing their internal clock date
change variable names and placement to be more readable and organized
this commit adds a temporation interface for starting gossip.
we needed this so we can start gossip AFTER setting up the node,
but before waitingForJoins.
port mapper gives out ports from 63000-65000 for the tests
fix another race
http test uses port.MustGetPort
rbf: remove :0 port request
ocd happy
test fix for grpc listener address already in use
test/disco allocates BindGRPC port from the port mapper
dump stack on each GetPort
verify each port is usable right away
server/config.go has Config.Validate() now
panic if gossip port is 0. validate server.Config
fix another gossip port 0
builds
quiet, don't dump stack on each port alloc
builds
happy linter
even gossip fallback should not be zero but rather use the port mapper
moved lonquerytime from cluster into server and moved cluster.longquerytime into top level config
kept cluster.longquerytime for backwards compatibility, favored if both longquerytime options are present
