simplify graph element naming convention

[tfjmp]

We should consider simplifying the graph naming convention to be more intelligible for the average user.

cred -> process task -> thread etc.

I will discuss with @michael-hahn and come up with something that does make sense.

We will be modifying entity, activity, and relationship names listed here, if necessary. We may also consider:

1. Reduce the number of relation types. Are they all necessary to keep?
2. Create relationship types and subtypes to provide different granularities of capture

Current relation types are:

• [ ] unknown ->
• [ ] read ->
• [ ] read_ioctl ->
• [ ] write ->
• [ ] write_ioctl ->
• [ ] clone_mem ->
• [ ] msg_create ->
• [ ] socket_create ->
• [ ] socket_pair_create ->
• [ ] inode_create ->
• [ ] setuid ->
• [ ] setpgid ->
• [ ] getpgid ->
• [ ] sh_write ->
• [ ] memory_write ->
• [ ] bind ->
• [ ] connect ->
• [ ] connect_unix_stream ->
• [ ] listen ->
• [ ] accept ->
• [ ] open ->
• [ ] file_rcv ->
• [ ] file_lock ->
• [ ] file_sigio ->
• [ ] version_entity ->
• [ ] munmap ->
• [ ] shmdt ->
• [ ] link ->
• [ ] rename ->
• [ ] unlink ->
• [ ] symlink ->
• [ ] splice_in ->
• [ ] splice_out ->
• [ ] setattr ->
• [ ] setattr_inode ->
• [ ] accept_socket ->
• [ ] setxattr ->
• [ ] setxattr_inode ->
• [ ] removexattr ->
• [ ] removexattr_inode ->
• [ ] named ->
• [ ] addressed ->

• [ ] receive_msg ->
• [ ] receive_msg_queue ->
• [ ] perm_read ->
• [ ] perm_write ->
• [ ] perm_exec ->

• [ ] terminate_task ->
• [ ] terminate_proc ->
• [ ] free ->
• [ ] arg ->

• [ ] ptrace_attach ->
• [ ] ptrace_read ->
• [ ] ptrace_attach_task ->
• [ ] ptrace_read_task ->
• [ ] ptrace_traceme ->

Current entity and activity types are:

• [ ] unknown ->
• [ ] string ->
• [ ] task ->
• [ ] inode_unknown ->
• [ ] link ->
• [ ] file ->
• [ ] directory ->
• [ ] char ->
• [ ] block ->
