1. Explain what the PR does

• change gRPC and HTTP flags to server
• refactor tracee, tracee-ebpf, tracee-rules to align with the new server flag format
• squash grpc-listen-addr, http-listen-addr to the same flag

a645543 added simple implantation of server flag

2375a0c974 fix: server flag is not inflags package

The reason why `pkg/cmd/flags/server` was like this.because tracee rules uses
this code, and doesn't compile libbpfgo and isn't dependant on libbpf go,
if we import 'pkf/cmd/flags' directly libbpfgo becomes a dependency and we need to compile it with
tracee-rules.

because tracee-rules will be removed shortly I move server pkg to flags

221d066 remove grpc flag file

grpc is part of the server flag. removeal of unnecassary code

edb2fd1 fix: tracee-ebpf, tracee-rules dowsnt support new flag format

change tracee --grpc-listen-addr and --http-listen-addr flag to --server
flag

tracee-ebpf and tracee-rulse supported the old foramt, made them support
the new flag format

2. Explain how to test it

Run tracese on your local machine with the server flag according to the new design, as described in the help section and docs.

this is the new design for the server flags:

--server http.metrics=<true/false>
--server http.pprof=<true/false>
--server http.healthz=<true/false>
--server http.pyroscope=<true/false>
--server http.address=<address>
--server grpc.address=<address>

this is the new design for the server config file:

server:
  http:
    metrics: false   # Enable metrics endpoint
    pprof: false     # Enable pprof endpoints
    healthz: false   # Enable health check endpoint
    pyroscope: false # Enable Pyroscope agent
    address: ":3366" # Set HTTP server listening address (default ":3366" when not set)
  grpc:
    address: ""      # Set gRPC server listening address (default: disabled)

you can also run the test under /tracee/pkg/cmd/flags

3. Other comments

This Pr moves the server flag from its package to the flags that have some performance issues on tracee-rules
