running out of 7 GiB memory for GitHub hosted runner

[cataggar]

I'm trying to compile azure_mgmt_compute with --all-features, but the GitHub hosted runner with 7 GiB appears to be running out of memory, getting an error like #51309. This is happening with a few crates. I've tested on stable rustc 1.56.0 & 1.55.0.

cargo check --manifest-path services/mgmt/compute/Cargo.toml --all-features

    Checking azure_mgmt_compute v0.1.0 (/home/runner/work/azure-sdk-for-rust/azure-sdk-for-rust/services/mgmt/compute)
error: could not compile `azure_mgmt_compute`

To reproduce, run in a GitHub workflow:

git clone https://github.com/Azure/azure-sdk-for-rust.git
cd azure-sdk-for-rust
cargo check --manifest-path services/mgmt/compute/Cargo.toml --all-features

I'm hoping there is a way to cap rustc memory and have the compilation take longer.

rustc 1.56.0 & 1.55.0

I'm going to throw more RAM at this problem. The macos hosted runner has 14 GiB.
