Support dnf-based installs and PATH checks for Azure Linux and RHEL-family hosts

[Copilot]

install.sh and uninstall.sh assumed Debian/Ubuntu package tooling, blocking Azure Linux and other dnf-based hosts from installing and removing Azure CLI cleanly.

• Distro and package-manager detection

  • Detects apt-get vs dnf.
  • Recognizes Ubuntu, Azure Linux/azlinux, Rocky, AlmaLinux, and RHEL support paths.
  • Parses /etc/os-release without sourcing it.

• Install path

  • Installs Azure CLI through the existing Debian installer on apt hosts.
  • Configures the official Azure CLI dnf package source at /etc/yum.repos.d/azure-cli.repo, then installs azure-cli with dnf.
  • Warns when /usr/local/bin is missing from the active PATH.
  • Leaves host prerequisites such as systemd-container to be provisioned outside the installer.

• Uninstall path

  • Removes Azure CLI via apt or dnf, preserving best-effort cleanup behavior.

# dnf hosts now use native package operations for Azure CLI
dnf install -y azure-cli
dnf remove -y azure-cli

Addressed in f54a89a by configuring the Azure CLI dnf package source directly via /etc/yum.repos.d/azure-cli.repo before running dnf install -y azure-cli.

@copilot can we also ensure /usr/local/bin is in $PATH?

Addressed in 5a2eaa1 by configuring /usr/local/bin in the installer PATH and persisting it via /etc/profile.d, with uninstall cleanup for the added profile snippet.

@copilot revert the path profile change, print a warning if /usr/local/bin is not in PATH variable instead.

Addressed in 1083206 by removing the PATH profile persistence/cleanup and warning when /usr/local/bin is missing from PATH.
