* [azure-core-cpp] Update to 1.8.0
## 1.8.0 (2023-02-02)
### Features Added
- Added support for parsing space character in place of 'T' in RFC3339 DateTimes.
- Added support for HTTP proxy servers, both unauthenticated and with basic authentication.
- Added universal support for several TLS options:
- Added the ability to set the expected TLS root certificate for TLS connection (useful if a proxy server uses a TLS certificate that is not chained to a known root).
- Added the ability to enable TLS certificate revocation list checks (off by default).
- For libcurl only: Allow TLS connection to succeed if CRL retrieval fails.
- *NOTE*: This change only applies if libcurl is built using the OpenSSL crypto backend. It does NOT apply if libcurl uses the schannel (Windows default) or SecureTransport (macOS/iOS default).
### Breaking Changes
- Changed the name of several distributed tracing HTTP span attributes:
- `requestId` is renamed to `az.client_request_id`
- `serviceRequestId` is renamed to `az.service_request_id`
- Bearer token authentication will not work for endpoint URL protocol schemes other than `"https"`. This ensures token security and is consistent with the Azure SDKs for other languages.
- Removed `noexcept` specification from `Azure::DateTime::clock::now()`.
- Updated retry policy timeouts to conform to Azure guidelines.
- The default delay between retries is changed from 4 seconds to 800ms.
- The maximum retry delay is changed from 2 minutes to 60 seconds (one minute).
If the original behavior is desired, customers can adjust these timeouts by changing the `RetryDelay` and `MaxRetryDelay` fields in the `RetryOptions` structure.
### Bugs Fixed
- Fixed bug in WinHTTP client which caused the `IgnoreUnknownCertificateAuthority` and `EnableCertificateRevocationListCheck` fields to be ignored if they were passed in from `TransportOptions`.
- [[#4206]](https://github.com/Azure/azure-sdk-for-cpp/issues/4206) Fixed connectivity issues in libcurl HTTP transport which can occur if a TCP connection is dropped prematurely. (A community contribution, courtesy of _[ahojnnes](https://github.com/ahojnnes)_)
### Other Changes
- Update distributed tracing attributes to align with current Azure Distributed Tracing Conventions attributes and names.
- Added the ability to consume version 1.1.1n of OpenSSL.
- Added support for Identity token caching, and for configuring token refresh offset in `BearerTokenAuthenticationPolicy`.
- Improved cancellation support for WinHTTP transport.

## 12.6.0 (2022-09-06)
### Features Added
- Features in `12.6.0.beta.1` are now generally available.
### Bugs Fixed
- Empty file or existing file won't be created/overwritten if the blob to be downloaded doesn't exist.
Since it first tries to locate the directory and then unconditionally
adds a subdirectory to it, running this script twice resulted in an
incorrect path (the last node was added multiple times).
We now check whether the script already ran and then abort.

### Breaking Changes
- Renamed `AttestationOpenIdMetadata` type to `OpenIdMetadata`.

purpose of the type.
- Removed the `AttestationTokenBase` class and moved its contents to the `AttestationToken` class.
- Empty `AttestationToken` types are now represented with `AttestationToken<void>` rather than `AttestationToken<>` to more idiomatically express the idea of a nullable attestation token.
- Renamed `RuntimeClaims` field to `RunTimeClaims` to align with `InitTimeClaims` type name; standardized spelling of
`InitTimeClaims`.
- Changed input parameter to `AttestTpm` to be `AttestTpmOptions` instead of `std::string`.
- Changed output parameter of `AttestTpm` to be `TpmAttestationResult` instead of `std::string`.

to improve consistency with other attestation SDKs.
- Removed the unused `AttestationValidationCollateral` API.
- Renamed `AttestOptions` to `AttestEnclaveOptions`
- Renamed `TokenValidationOptions` field in various API Options structures to be `TokenValidationOptionsOverride` to better
reflect the semantics of the field.

- `PolicyCertificateModificationResult` becomes `IsolatedModeCertificateModificationResult`
- `PolicyCertificateListResult` becomes `IsolatedModeCertificateListResult`
- `GetPolicyManagementCertificateOptions` becomes `GetIsolatedModeCertificatesOptions`
- `AddPolicyManagementCertificatesOptions` becomes `AddIsolatedModeCertificatesOptions`
- `RemovePolicyManagementCertificatesOptions` becomes `RemoveIsolatedModeCertificatesOptions`
- `AttestationAdministrationClient::GetPolicyManagementCertificates` becomes `AttestationAdministrationClient::GetIsolatedModeCertificates`.

- `AttestationAdministrationClient::RemovePolicyManagementCertificate` becomes `AttestationAdministrationClient::RemoveIsolatedModeCertificate`.
- Removed `ClientVersion` API from `AttestationClient` and `AttestationAdministrationClient`
### Other Changes

## 1.5.0 (2022-03-31)
### Features Added
- When a `RequestFailedException` exception is thrown, the `what()` method now includes information about the HTTP request which failed.
- Adding option `WinHttpTransportOptions.IgnoreUnknownCertificateAuthority`. It can be used to disable verifying server certificate for the `WinHttpTransport`.
### Breaking Changes
- Enforce TLS 1.2 or greater for `CurlTransport` and `WinHttpTransport`.
### Other Changes
- Improve output message for `Azure::Core::Http::TransportException`.
