Refactoring the timeout retries into a more general 'retry policy' with
support for retrying on HTTP 429 (Too Many Requests) and other responses
with a `Retry-After` header
The delay between requests is controlled by a combination of a 'backoff'
(currently only a simple linear backoff), and honouring the
`Retry-After` value (longest delay wins)
This makes the 'rate limiter' an optional argument as well, removing the
use of `nil` when one isn't supplied

- Modifications made to the request package. Planned improvements will be
sending requests on intervals, rate limiter back off support, dynamic tuning
and requests packaged into a request job group.
- Can modify each exchanges individual HTTP client (e.g timeout and
transport settings).
- Bot now uses an exchange config HTTP timeout value.
- Bot now uses a global HTTP timeout (configurable).
- Batched ticker request support for exchanges.
- Ticker and Orderbook fetching now are spanned accross multiple
go routines and regulated by a sync wait group.
- Fixes hack used to load exchanges, now uses a sync wait group.
- Ticker and Orderbook storage and fetching now uses mutex locks.
- New pair function for finding different pairs between two supplied
pair arrays. This is used for currency pair updates for exchange which
support dynamic updating.
- Shows removal/additions of dynamic updates currencies.
