New users to helm don't always run `helm init` (e.g. if their cluster
already has helm installed).  The user's initial interaction with any of
helm's repository commands (e.g. `helm repo list`) will then be an error
message due to a missing repositories.yaml in their local config.

Give the user a little hint about how to fix the error without them having
to hunt through the man/help pages.

This reverts commit 965cb7fd.

This prevents clients from seeing half-written files because
on POSIX systems renaming a file is an atomic operation.

Drive-by: Add test for repo file permission.

Closes #1522

This prevents the index command from recursing through directories.
Behind the scenes, it swaps out the repository logic for the index file
logic.

Closes #1328

Between Alpha.4 and Alpha.5 there was a change in the indexing logic.
This prevent indices from being appended to (because those index files
were often broken). This change allows the user to explicitly merge an
existing index and a generated index.

Closes #1334

This implements a new index file format for repository indices. It also
implements a new format for requirements.yaml.

Breaking change: This will break all previous versions of Helm, and will
impact helm search, repo, serve, and fetch functions.

Closes #1197

This also refactors significant portions of the CLI, moving much of the
shared code into a library.

Also in this release, a testing repository server has been added.

Use the same format as the Open Container Initiative for a digest
string. https://github.com/opencontainers/image-spec/blob/master/descriptor.md#digests-and-verification
