Extend `box.cfg.audit_spaces`

[TarantoolBot]

Since: 3.7

Each element of box.cfg.audit_spaces used to be a string representing
a space name. Now it also can be a table with the following fields:
- name - mandatory, name of the space.
- extract_key - optional, has the same semantics as option
audit_extract_key, but for particular space.

Also, space name can be a wildcard. It describes all spaces except for ones
listed in audit_log.spaces.

Example:

box.cfg({
    audit_log = 'audit.log',
    audit_format = 'csv',
    audit_filter = 'dml',
    audit_spaces = {
        {name = 'space1', extract_key = true},
        {name = 'space2', extract_key = true},
        '*' -- Enable all other spaces.
    }
})

box.schema.space.create('space1')
box.space.space1:create_index('primary')
box.schema.space.create('space2')
box.space.space2:create_index('primary')
box.schema.space.create('space3')
box.space.space3:create_index('primary')

box.space.space1:insert({1}) -- primary key is logged
box.space.space2:insert({2}) -- primary key is logged
box.space.space3:insert({3}) -- full tuple is logged

os.exit(0)
