This PR addresses the following:
- Install and Configure protolint to enforce the protobuf style guide rules in the CI.
- Fix the protolinting issues (package and import ordering) while maintaining the comaptibility.
The docker image have been updated so we are using another protobuf
version to generate the files. The generate files include the version of
the compiler used to creating them, so we need this commit to pass the
`rpc-check` step in our CI.
Move merge of our features into the feature manager, rather than
updating our node announcement then retrospectively setting the
feature manger's set to the new vector. This allows us to use the
feature vector as our single source of truth for announcements.
In preparation for a more complex function signature for set node
announcement, separate get and set so that readonly callers don't need
to handle the extra arguments.
Use kvdb package v1.4.1. This update also forced the protobuf version to
be bumped which required `make rpc` to be run to update the generated
files. This also required a bump in the github pinned dependencies
config for the grpc and protobuf libs.
The `log.go` file of each subserver is a copy and paste of the others.
All of them have the same typo, an extra space in a comment, and the
the definition of a function not used anywhere.
