Reformat the Bazel build files with the buildifier tool [1].

is 4 spaces instead of 2, and " is used instead of '.

This commit implements the basic class structure for receiving emails,
all required config parameters, all necessary bindings depending on
which protocol the administrator has configured and updates the
documentation accordingly.
It also adds test-only dependencies to Greenmail and javax.mail. These
will be used to create integration tests.
It's the first change in a topic of changes to implement email ingestion
for Gerrit.
