Michael Kelly c34b91c9d8 manifest: Support ignoring local manifests with 'repo manifest'
Currently users need to look up the baseline manifest by loading the
specific manifest file.  This exposes them to the internals of how the
manifest is stored which may potentially be fragile (eg: It was
switched from a symlink pointing at the file in the report to an
actual file with an 'include' tag).

Instead of doing this, we can provide an option to the 'repo manifest'
command which will emit the baseline manifest and decouple users from
the internal manifest details.

With the -o option, exports the current manifest for inspection.
The manifest and (if present) local_manifests/ are combined
together to produce a single manifest file. This file can be stored
in a Git repository for use during future 'repo init' invocations.
The -r option can be used to generate a manifest file with project
revisions set to the current commit hash. These are known as
"revision locked manifests", as they don't follow a particular branch.
In this case, the 'upstream' attribute is set to the ref we were on
when the manifest was generated. The 'dest-branch' attribute is set
to indicate the remote ref to push changes to via 'repo upload'.
