* ecc: add the support for ECC
update generate_private_key to support ECC. Move key types to constant. Update UI for the new key types
* ecc: Remove extra line to fix linting
* ecc: Fix flake8 lint problems
* Update options.tpl.html
* UI adjustments to make Key Agreement, Encipher Only, and Decipher Only relationship more user-friendly
* whitespace typo
* Issue #663 switching Encipher/Decipher Only options to be mutually exclusive and un-checkable radio buttons.
* Found a bug in the fields schema that was dropping Key Agreement bit if encipher/decipher only weren't checked
* Allowing that create_csr can be called with an additional flag in the csr_config to adjust the BasicConstraints for a CA.
* If there are no SANs, skip adding a blank list of SANs.
* Adding handling for all the extended key usage, key usage, and subject key identifier extensions.
* Fixing lint checks. I was overly verbose.
* This implements marshalling of the certificate extensions into x509 ExtensionType objects in the schema validation code.
* Will create x509 ExtensionType objects in the schema validation stage
* Allows errors parsing incoming options to bubble up to the requestor as ValidationErrors.
* Cleans up create_csr a lot in the certificates/service.py
* Makes BasicConstraints _just another extension_, rather than a hard-coded one
* Adds BasicConstraints option for path_length to the UI for creating an authority
* Removes SAN types which cannot be handled from the UI for authorities and certificates.
* Fixes Certificate() object model so that it doesn't just hard-code only SAN records in the extensions property and actually returns the extensions how you expect to see them. Since Lemur is focused on using these data in the "CSR" phase of things, extensions that don't get populated until signing will be in dict() form.* Trying out schema validation of extensions
* Aligning certificate creation between authority and certificate workflows
* Correctly missing and mis-named fields in schemas
* Re-ordering KeyUsage and ExtendedKeyUsage for consistency and clarity
* Adding client authentication to the authority options.
* Missing blank lines for pyflakes linting
* Updating tests for new fields/names/typos
* is_critical wasn't in the schema, so was getting dropped.
* isCritical in the Javascript wasn't getting assigned if it was unchecked. Now, it will be assumed false if missing.
* The display of critical or not in the list of added custom OIDs was unclear when it was just true/false with no heading. Now it will be displayed as critical or nothing instead.
* The namespace for the checkbox for isCritical was wrong, and didn't get processed with the oid/type/value variables.
