[rustls] identity: handle elliptic curve private keys #1526

This commit improves the user experience of the users leveraging rustls.

When building the identity to use for requests, it's now possible to use also private keys using Elliptic Curve that are encoded with SEC1 standard.

This is the default encoding used by openssl when EC keys are created. Prior to this commit users had to convert those keys from the SEC1 encoding to the PKCS 8 one, which is something not trivial.

This feature has been recently added to rustls-pemfile crate. This commit update the rustls-pemfile crate to its latest stable release.

I also had to change a little the code used to extract the private keys from the PEM file. That's because rustls-pemfile doens't provide a high level API that extracts Elliptic Curve keys.

Thanks for the PR! I'm generally pro on this addition. I'm starting to worry about a bunch of this TLS code that doesn't really have tests, but that's not the fault of this PR. More just me worrying... Anyways, I think this just needs a rebase, since I already merged a different PR that updated the dependency version.

I get it... thanks for being positive about this PR
