To allow nodes more control over the amount of time that their funds
will be locked up, we add a MaxLocalCSVDelay option which sets the
maximum csv delay we will accept for all channels. We default to the
existing constant of 10000, and set a sane minimum on this value so that
clients cannot set unreasonably low maximum csv delays which will result
in their node rejecting all channels.
Because we'll add a check that enforces all command line flags that are
available with the default build tags to also be contained in the
sample-lnd.conf file, we first add all that currently are missing.
This commit removes the duplicate tor.streamisolation option from `sample-lnd.conf` example config file (which was accidentally added in commit #104a9094980f31560ca269d3b01f000dd775778d)
This commit enables lnd to request and renew a Let's Encrypt
certificate. This certificate is used both for the grpc as well as the
rest listeners. It allows clients to connect without having a copy of
the (public) server certificate.

- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC

When starting up with lnd.conf that contains the sample line
"tor.active", lnd crashes and prints the error:
malformed key=value (tor.active)
Using "tor.active=true" instead works as expected.
In this commit, we update the `sample-lnd.conf` example config file to
be up to date with all the new configuration parameters we've added over
the past few release.
Add a new health check package which will periodically poll health
check functions and shutdown if we do not succeed after our set number
of attempts. The first check that we add is one for our chain backend,
to ensure that we are connected to a bitcoin node.
Since https://github.com/lightningnetwork/lnd/pull/506, `defaultchanconfs` is nested under `bitcoin`. Using this parameter at the top level generates a warning message:
```
2018-03-17 23:07:08.273 [WRN] LTND: /home/bitcoin/.lnd/lnd.conf:7: unknown option: defaultchanconfs
```
and using it nested under `bitcoin` does not.
