v1.4.2

Allow disabling the writes of ephemeral nodes to storage via the --tree_ids_with_no_ephemeral_nodes flag to the sequencer.

• Allow not storing ephemeral node hashes by @pavelkalinnikov in #2568
• Log skipped ephemeral nodes writes by @pavelkalinnikov in #2756

Developer updates

• #2765 copies the required protos from googleapis into third_party in this repository. This simplifies the preconditions in order to compile the proto definitions, and removes a big dependency on $GOPATH/src which was archaic; $GOPATH/src/github.com/googleapis/googleapis is no longer required.

• Propagate Log Update Failures in AddSequencedLeaves by @therealdrake in #1544
