routing: if MaxShardAmt is set, then use that as a ceiling for our splits
In this commit, we thread through the necessary state to allow users to
set a max shard amount. If this value is set, then this'll effectively
serve as a ceiling for all our split attempts. If we need to split,
we'll first try to use `paymentAmt/2`, if that's bigger than
`MaxShardAmt, then we'll use the latter instead.

Ideally in the future we have a dynamic way to automatically set both
the `MaxShardAmt` as well as `MaxParts` for users. Until then exposing
these two new fields will allow us to experiment with setting them
automatically using the RPC interface, and also give users a bit more
control over how we attempt to route payments, akin to coin control for
on-chain payments.

Fixes #4730

routing: allow custom dest feature bits in integratedRoutingContext.testPayment
This is a preparatory commit for a new test to ensure that if a node
only has the TLV and payment addr feature bits, we don't try to split a
payment.

router: move self node out of config
We are going to use the config struct to allow getting and setting
of the mission control config in the commits that follow. Self node
is not something we want to change, so we move it out for better
separation.

kvdb: add timeout options for bbolt (#4787)
* mod: bump btcwallet version to accept db timeout

* btcwallet: add DBTimeOut in config

* kvdb: add database timeout option for bbolt

This commit adds a DBTimeout option in bbolt config. The relevant
functions walletdb.Open/Create are updated to use this config. In
addition, the bolt compacter also applies the new timeout option.

* channeldb: add DBTimeout in db options

This commit adds the DBTimeout option for channeldb. A new unit
test file is created to test the default options. In addition,
the params used in kvdb.Create inside channeldb_test is updated
with a DefaultDBTimeout value.

* contractcourt+routing: use DBTimeout in kvdb

This commit touches multiple test files in contractcourt and routing.
The call of function kvdb.Create and kvdb.Open are now updated with
the new param DBTimeout, using the default value kvdb.DefaultDBTimeout.

* lncfg: add DBTimeout option in db config

The DBTimeout option is added to db config. A new unit test is
added to check the default DB config is created as expected.

* migration: add DBTimeout param in kvdb.Create/kvdb.Open

* keychain: update tests to use DBTimeout param

* htlcswitch+chainreg: add DBTimeout option

* macaroons: support DBTimeout config in creation

This commit adds the DBTimeout during the creation of macaroons.db.
The usage of kvdb.Create and kvdb.Open in its tests are updated with
a timeout value using kvdb.DefaultDBTimeout.

* walletunlocker: add dbTimeout option in UnlockerService

This commit adds a new param, dbTimeout, during the creation of
UnlockerService. This param is then passed to wallet.NewLoader
inside various service calls, specifying a timeout value to be
used when opening the bbolt. In addition, the macaroonService
is also called with this dbTimeout param.

* watchtower/wtdb: add dbTimeout param during creation

This commit adds the dbTimeout param for the creation of both
watchtower.db and wtclient.db.

* multi: add db timeout param for walletdb.Create

This commit adds the db timeout param for the function call
walletdb.Create. It touches only the test files found in chainntnfs,
lnwallet, and routing.

* lnd: pass DBTimeout config to relevant services

This commit enables lnd to pass the DBTimeout config to the following
services/config/functions,
  - chainControlConfig
  - walletunlocker
  - wallet.NewLoader
  - macaroons
  - watchtower
In addition, the usage of wallet.Create is updated too.

* sample-config: add dbtimeout option

routerrpc+routing: adapt payment session for multi shard send
Modifies the payment session to launch additional pathfinding attempts
for lower amounts. If a single shot payment isn't possible, the goal is
to try to complete the payment using multiple htlcs. In previous
commits, the payment lifecycle has been prepared to deal with
partial-amount routes returned from the payment session. It will query
for additional shards if needed.

Additionally a new rpc payment parameter is added that controls the
maximum number of shards that will be used for the payment.

routing/test: test probability extrapolation
Adds an integrated routing test of probability extrapolation for untried
channels. The larger part of this commit is mock code to simulate the
Lightning Network.

The difference between this test and the existing pathfinding tests, is that
this test focuses on the feedback loop from result interpretation via
mission control updates and probability estimation back to pathfinding.
Improvements like probability extrapolation were previously only
validated by reasoning, while this setup makes it possible to assert the
improvement in a test and guard it for the future.
