Use term "bootstrap"

[akiradeveloper]

To add a new node, there should be an existing cluster to accept the joining. But how about the first node?

The first node is taken as a special node that forms a single node cluster with only itself.

Other softwares like elasticsearch and Consul seem to do the same thing and both call it bootstrapping.

• https://www.elastic.co/blog/a-new-era-for-cluster-coordination-in-elasticsearch: if you want to start a brand new cluster that has nodes on more than one host, you must specify the initial set of master-eligible nodes that the cluster should use as voting configuration in its first election. This is known as cluster bootstrapping
• https://www.consul.io/docs/architecture/consensus: When getting started, a single Consul server is put into "bootstrap" mode.

lol should use the same term.

lol-book is overhauled. It was a bit obsolete and unmaintained.
