add traceectl to tracee

[ShohamBit]

Description

This PR introduces traceectl, a new CLI tool for interacting with Tracee. It implements basic commands for communication with Tracee via gRPC.

Key Changes

• Added traceectl CLI tool.
• Implemented commands for:
  • version
  • metrics
  • stream
  • event

Testing

1. Compile and run Tracee with gRPC:

   make tracee
   sudo tracee --grpc-listen-addr unix:/tmp/tracee.sock

2. Run traceectl:

   cd ./cmd/traceectl
   sudo go run main.go stream

   This displays the help command.

Current Limitations

• metrics: JSON output is not yet supported.
• stream: Only the base stream command is supported. Streams events directly from Tracee.

Related Issues

Please see comments below.
In addition, please add documentation to traceectl.
As part of the documentation, please also refer to the way the user should start tracee "daemon" (e.g. using NONE output and setting the grpc server address)

What do you think about adding a flag to traceectl version command called short for a short version instead of all the info we get, or the exact offset making the long flag and the short version the default?

@ShohamBit @yanivagman what do you think about splitting this? Since we already have a working stream command, we could open a PR with just the base root and stream commands to establish a foundation for the upcoming new commands (each added in separate PRs). This approach would make both implementation and review more manageable.

Hey @geyslan, great thinking, let's discuss this over with @yanivagman
