separate namespaces.

multi: add reset closure to kvdb.Update
Similarly as with kvdb.View this commits adds a reset closure to the
kvdb.Update call in order to be able to reset external state if the
underlying db backend needs to retry the transaction.

multi: add reset closure to kvdb.View
This commit adds a reset() closure to the kvdb.View function which will
be called before each retry (including the first) of the view
transaction. The reset() closure can be used to reset external state
(eg slices or maps) where the view closure puts intermediate results.

d3545830c9 kvdb+etcd: integrate the abort context to the STM retry loop
This commit extends the etcd.BackendConfig to also provide an abort
context and integrates it with the STM retry loop in order to be able
stop LND when conflicting transactions keep the loop running.

c3fcfd1530 etcd: add namespace support to separate key spaces
This commit extends etcd db with namespaces without additional storage
space requirements. This is simply done by instead of using an all zero
root bucket id, we use the sha256 hash of the name space as our root
bucket id.

85aee9b064 kvdb+lncfg: fully move etcd behind build tag
This commit separates all etcd related sources (sans a few stubs and
config) from the rest of the source tree and makes compilation conditional
depending on whether the kvdb_etcd build tag is specified.

137dee04e8 channeldb+kvdb: an extended STM on top of etcd clientv3
This commit adds an extended STM, similar to what available in etcd's
clientv3 module. This incarnation of said STM supports additional
features, like positioning in key intervals while taking into account
deletes and writes as well. This is a preliminary work to support all
features of the kvdb interface.
