Added storage config setting

[robgaskell]

Added a config item to allow the changing of the ephemeral storage value, used when deploying sidecar-browsershot.

The storage method, which is used by sidecar, returns the value as set in the config. If the config item does not exist, for example if the config has not been updated after this release, the default sidecar value is used.

Thanks for the PR.
I don't quite understand, why we need to add this in this package.
If you upgrade wnx/sidecar-browsershot one would also automatically update hammerstone/sidecar.

Or did you run into issues, where this config became a problem?
The config is related to aarondfrancis/sidecar#71, right?

I needed to update the storage for sidecar-browsershot without changing the setting for other sidecar deployed items.

We were getting exceptions such as the following when generating pdfs:

Lambda Execution Exception for Wnx\SidecarBrowsershot\Functions\BrowsershotFunction: "ENOSPC: no space left on device, write. [TRACE] Error: ENOSPC: no space left on device, write at Object.writeSync (fs.js:737:3) at Object.writeFileSync (fs.js:1535:26)".

The PR overrides the method as suggested in the sidecar docs, but using a config item specific to the package, in exactly the same way overriding the default memory config works.

I see, thanks for the explanation.
Yeah having multiple sidecar function and managing the settings for each isn't perfect yet.

Will merge and tag a new version shortly.
