Before this if the client_id/client_secret was edited it would
disappear when asking for the new token.
This means the post config is done after the user has confirmed the
config is OK which can't be helped.
RepeatableReaderSized has a pre-allocated buffer which should help
with memory usage - before it grew the buffer. Since we know the size
of the chunks, pre-allocating it should be much more efficient.
RepeatableReaderBuffer uses the buffer passed in.
RepeatableLimit* are convenience funcitions for wrapping a reader in
an io.LimitReader and then a RepeatableReader with the same buffer
size.
Now --dump-flag is written as --dump flag. This is a comma separated list which can contain
* headers - HTTP headers as before
* bodies - HTTP bodies as before
* requests - HTTP request bodies
* responses - HTTP response bodies
* auth - HTTP auth
* filters - Filter rexeps
Leave --dump-headers and --dump-bodies for the time being but remove
the other --dump-* flags as they aren't used very often.
This was leaking goroutines in the short file case beause it wasn't

Previously config sub commands were manually parsed rather than using
cobra.
Make config command have the following sub commands:
* create Create a new remote with name, type and options.
* delete Delete an existing remote <name>.
* dump Dump the config file as JSON.
* edit Enter an interactive configuration session.
* file Show path of configuration file in use.
* providers List in JSON format all the providers and options.
* show Print (decrypted) config file, or the config for a single remote.
* update Update options in an existing remote.
The following changes were made to existing commands
* listproviders was renamed to providers
* listoptions was removed in favour of providing the output in providers
* jsonconfig was renamed to create
* an optional parameter was added to the show command
